First Time Leaving Your Baby With a Babysitter: The Complete Checklist

The first time you leave your baby with a sitter, you need to leave behind more than a phone number on the fridge. Your sitter needs feeding instructions, emergency contacts, medical details, and enough context to make good decisions without you in the room. The preparation takes about 20 minutes. The confidence it buys you is worth far more than that.

This is the complete checklist for first-time parents handing off to a new babysitter — whether it is a trusted friend, a recommended sitter, or a first date with a professional babysitter.

Why the first handoff is the most important one

A new sitter has no baseline. She has never seen your baby when he is hungry versus tired versus just fussy. She does not know the specific cry, the specific hold, the specific song. Every bit of that institutional knowledge that you have built over months has to be compressed into a handoff conversation and a written reference she can find in a pinch.

The written reference matters most. In a stressful moment — baby screaming, milk spilled, something not quite right — she is not going to call you and wait. She is going to look for something written down. If it is not there, she will improvise. Give her something to find.

What your sitter needs to know about feeding

Feeding is the first place things go wrong with infant care. Be specific about every detail:

Breast milk or formula — which, how much, and how often. If breast milk, which bags in the fridge, and whether they are labeled in order.
How to warm it — bottle warmer, bowl of warm water, or room temperature. Never microwave breast milk.
How to know when the baby is hungry — describe the specific cues your baby shows before crying: rooting, hand-sucking, fussing in a particular way.
How to tell when the baby is full — turns away, loses suction, relaxes hands.
Burping method — how long, which position works for your baby.
Solids, if relevant — what foods are on the approved list, what is not yet introduced, and any early reactions to watch for.
Any feeding quirks — prefers a specific nipple size, needs a certain position, gets gassy with fast feeding.

What to share about sleep

Safe sleep setup — back on a firm, flat surface, nothing in the crib (no blankets, no stuffed animals, no positioners).
Nap schedule — how many naps, typical timing, how long each usually lasts.
Sleep cues — yawning, eye rubbing, staring, getting quiet. The window between sleepy and overtired is short at this age.
How you settle the baby — rocking, swaying, pacifier, white noise machine, specific song. Be honest: if you nurse to sleep, say so and have a backup plan for the sitter.
Where the baby sleeps — crib, bassinet, pack-and-play. Show the sitter before you leave.

Medical information the sitter must have

Even healthy babies need this information documented before you leave:

Pediatrician's name and number — office line and after-hours line.
Any known allergies — including early reactions to any food if you have started solids.
Any current medications — name, dose in milliliters, when to give it, whether it requires a call to you first.
Any conditions — reflux, colic, milk protein intolerance, heart murmur under monitoring — and what the sitter should do if it flares.
Health insurance card — leave a photo or copy she can access quickly.
Your child's full name and date of birth — in writing, not just verbal. An ER intake form will ask for it.

Emergency contacts — more than just your number

Your number alone is not enough. You might be in a loud restaurant, driving, or in a movie. Give her a complete contact list:

Your cell phone — and tell her to call, not text, in an emergency.
Your partner or co-parent
A local backup adult — someone who can be at your house in 10 minutes if she cannot reach you.
Your pediatrician — with the after-hours number specifically highlighted.
Poison Control — 1-800-222-1222 (United States).
Your location — not just "dinner." The name and address of where you are going.

Make the rule explicit: for any medical concern, she calls you first, then the pediatrician. For breathing issues, unconsciousness, or anything severe, she calls 911 first and you immediately after.

What to walk through in person before you leave

A written document covers the facts. A five-minute walkthrough covers the feel. Before you hand the baby over:

Show her the crib setup and confirm she knows safe sleep rules.
Open the fridge together and point to the labeled milk bags.
Show her where the diapers, wipes, and spare outfits are.
Let her hold the baby while you are still there — some babies protest the transition more than others, and it is better to know that while you are in the room.
Point to wherever your written information is. Do not assume she will find it; show her.
Tell her the one thing most likely to make this evening hard (overtiredness, missed nap, teething) and what helps.

How to make the goodbye go smoothly

For very young babies, a dramatic goodbye can make things harder. Keep it brief and confident. Babies at this age are more responsive to your emotional state than you expect — if you are visibly anxious at the door, the handoff will go worse. Hand the baby over, say something confident to both of them, and leave.

Tell the sitter the text check-in cadence you prefer. Some parents like a photo at the first nap. Others prefer to not be messaged unless something is wrong. Either is fine — just be explicit so she is not guessing.

Frequently Asked Questions

How much information is too much to give a babysitter?

There is no such thing as too much when it is organized. The problem is not information volume — it is information buried in a way that is hard to act on. A five-page document where allergies are on page four is more dangerous than a one-page sheet where allergies are at the top. Organize by priority and let the sitter skim to what matters.

What should I do if my baby cries for an extended time with the sitter?

Leave the sitter with a clear protocol: if she has tried feeding, burping, a diaper change, and soothing for 20-30 minutes and the crying is escalating or different from normal, she should call you. If the crying is accompanied by any change in breathing, color, or the baby seems inconsolable in an unusual way, call the pediatrician or 911 before calling you.

Should I leave a written medical consent form for the babysitter?

Yes, especially if there is any chance the sitter might need to seek medical care. A written consent form with your signature, the child's name and date of birth, and explicit authorization for the sitter to consent to emergency medical treatment is valuable. Hospitals may provide care without it in true emergencies, but having it removes friction. See our article on medical consent forms for babysitters for a full breakdown.

What age is a baby ready to be left with a new sitter?

There is no universal age — it depends on the child's temperament, the sitter's experience, and your comfort level. Most pediatricians suggest waiting until the baby is past the most fragile newborn period (6-8 weeks) before leaving with someone outside the immediate family, though many parents leave earlier. The key variable is how confident you are in the sitter's ability to handle the specific challenges of an infant.
