My little boy was on lactulose for 2 weeks and he's been off it for a while now and goes once/twice every 3-4 days. He's formula fed. I think it's just his normal. Does your baby seem distressed/straining?
not sure if this is still an issue now but babies can have an oz of cooled boiled water per day if they’re constipated! my health visitor fed my baby girl some water at 3weeks old and it helped so much x
@Nia BF babies shouldn't have water until 6 months
It's an absolute myth that BF babies don't poo as often. Babies should poo daily. It can be common they they don't, but it's not normal and it's important to try and work out the route cause. May be worth seeing a lactation consultant or your local infant feeding team x
