I wish I could help but our son always slept through night starting at 3 weeks old we had to wake up ourself just to make sure he had a feeding at night.
If it’s not for milk and everything is ok (confirm on monitor), consider letting her cry it out a little. It doesn’t need to be the whole night, but give her a pacifier and leave her alone for a little longer. Don’t pick her up, but only rub her tummy and shush when you give her the pacifier. If you go in to check on her/rub her belly, don’t talk to her and don’t make eye contact. That’s stimulation and will keep her up longer. Give a good sniff for poop, but if it’s just pee, also don’t change her diaper (diaper changes are very stimulating at this age)! I know in the middle of the night I just wanted to get my daughter quiet as soon as possible so we could all go back to sleep. These steps will take longer; it will be 3-7 days of worse sleep, but then it will (likely) get dramatically better. Consider doing this over a weekend or a time where you (or one of her caregivers) isn’t working so you can catch up on sleep. You’ve got this mama! It’s tough but it’s a phase.
Wherever you feed them good good and heavy
Ours has been sleeping through the night since he was one month old
Without feeds ?
We would just make sure he was good and full before he went to sleep. If he woke up for a bottle (which was only during growth spurts) then that was fine but other than that he would just sleep until 6am.
Are your babies sleep trained ?
My baby started sleeping through the night at 4 months. She started sleeping through the night when I allowed her to learn how to put herself back to sleep. Babies need to be given the opportunity to self soothe. Once I started doing that, she has been sleeping through the night. If we pick them up when they start crying, they don’t get a chance to learn how to self soothe.
It is different with each baby. We just let our son eat a hearty amount of baby oatmeal then do our kisses, lay him down in the crib, turn on his music and projector. We started him out in a bassinet for two months next to our bed, then moved to the pack n play and moved to the other side of the room, 1 week of pack n play in the livingroom, did a nap in the crib in his shared room with our oldest and now he won't sleep anywhere else. Try a diffuser with lavender essential oil. We also use Thermal-Aid Zoo - Mini Microwavable Stuffed Animal from Amazon when he won't settle. But he's been sleeping through the night since March and again it varies per baby.
