We had this with my daughter we found that she didn’t poop when she wasn’t getting enough. We swapped breast milk for formula before bed and it make such a difference. She has EBM the rest of the time xx
I think there's a point they stop pooping overnight and just wee instead?
A lot of babies get constipated too which is normal look at which formula she is having my 9 week old is on hungry babies as normal formula or anti reflux wasn’t filling her up enough but again constipation can be a common problem in babies but can get lactose from your doctor and give small amount once/twice a month 1/2ml so there bowels don’t get reliant on it
Keep an eye on her wet nappies if she's producing plenty of them thrn she's getting enough milk. Also keep a look out for hunger cues
