Hi, I wonder if anyone can help. This is my first baby and he is just over 3 weeks. He didn't have any issues pooing or passing wind but since he got constipation (I had to get him into formula from BF as I was on antibiotics) he has had issues every since. It took him 5 days to start pooing properly from the rabbit poo he had while constipated and it's been 2 days since of lovely poos. Since then though, he has started crying everytime he has been fed and needs to poop/ pass wind. It wakes him up and cries and screams until the feeling passes then goes back to sleep for a few minutes and then cries again.
I have tried infacol but that's not working. He burps fine but an hour or so after feeding, he starts up and looks in pain and the on/ off crying can last for ages. Yesterday evening he cried for 2 hours just cos he was trying to poo/ pass wind.
I know he isn't used to pooping as he didn't need to do that in the womb but he was absolutely fine until the last few days.
Help??!!!
