Oh dear, I understand how worrying this can feel, especially when you are not sure what is normal for your little one. For formula-fed babies, bowel movements can sometimes be less frequent than breastfed babies, but I think it is still best to get a proper check just to be sure everything is okay inside. Please do bring your baby to see the paediatrician soon, as the doctor will be able to advise you properly and give you peace of mind. Sending you lots of strength, mama, you are doing well for looking out for your baby!
