Should I be worrying

My 3 week old has been gaining weight and the midwife said that it’s ok to let him sleep for 4 hour stretches, but recommended waking him after 4ish hours. She told me that if he’s still gaining weight at 6 weeks old then I can let him sleep through longer.

We were advised to wake ours up every 3hrs but since he gained his birthweight back after his 1 month visit we’re told we can let him sleep and he regularly goes 4-5 hrs.

But I also know a couple (both wife and hubby are doctors, though not pediatricians) who ignored this advice from day 1 and let their baby sleep as much as it wanted.

Was it a very dramatic drop in percentile? Maybe you could get another opinion?

My little girl had her 6-week check 2 weeks ago and she’s gained weight but dropped in centile. She’s sleeping 7 hours some nights and the midwife told me to wake her to feed her. However I won’t be doing that as some nights she wakes for feeding multiple times she knows when she’s hungry and lets me know about it. I’m due to go see the health visitor on the 3rd of November for a weigh in but they also told me her weight wasn’t anything to be concerned about as she isn’t far off. Don’t help she did the biggest wee before getting weighed 😂

Baby's growth is not linear, if he's gaining weight and nappy output is good, let him (and yourself) sleep, you can't force a baby to eat more, they're super instinctive and know when they're hungry/full.

Also, health visitors are not medical professionals, and it can be really hit and miss whether or not they're good, if you're worried about your kid, talk to the doctor, if your gut tells you they're better off asleep, trust that and keep doing what you're doing!
