She needs to be eating every 2 hours so she's not gonna be sleeping through the night anytime soon. Heck, mine woke every few hours until she was 14 or 15 months.

girl the baby is 3 wks !!! no they do not sleep through the night. they still need to be eating .
my 27 month old still doesn't sleep through the night

A 3 week old isn’t supposed to sleep through the night. They’re still going to be up and down for a while because they need to eat frequently and they’re adjusting. Read up on the 4th trimester. It’ll get easier mama! I know it’s exhausting. Do you have help?

A 3 week old is NOT supposed to sleep through the night. They still need to be fed throughout the night. Read up on the 4th trimester and some baby development articles... please, for your baby’s sake.

She’s three weeks. She shouldn’t be expected to sleep through the night. She still needs to feed. My 8 month old still needs his night time feeds.

Patience! She has to adjust to being out. It should get better soon

I feel your pain! mine would wake up every 2 hours to eat til she was 2 months old... sleep was such a struggle especially since I was breastfeeding. I tried everything, a rock and play, a swing, white noise, rocking to sleep and none really worked. We bought one of those bassinet sort of things that can go on your bed so baby can sleep next to me and that thing helped her sleep longer and was easier on me. But tbh it’s prob just cause she is 3 weeks, it will get easier! I thought I would never have sleep but now that she is 5 months and not so newborn like anymore, I get 4 to 6 hours of sleep straight finally
