Hi ladies! My baby boy is one month old (he's formula fed- I'm not sure if this makes a difference) and for the past week he has been going anywhere between 24 &  48 hours (sometimes even more) without pooping. I can tell he's uncomfortable as he's crying, kicking his legs and his tummy is bloated 😔 last night he woke up screaming, farting and grunting. is there anything I can do to help him?
