Thanks for the replies ladies. We have the same situation again tonight.
I took DD back to the Dr this morning and he said her bowel felt alot less full than Tuesday which makes me wonder if the crying is caused by something else.

I've had her taking Coloxyl, Infants Movicol, trying to get her to drink as much fluid as possible but all she really wants is milk so i've only been giving her half bottles and watering it down along with a dose of coloxyl or movicol mixed in. I've tried prune juice which she flat out refused, I've been giving her fresh pears but she won't touch anything prune related.

The Dr told me to try a suppository so we did that tonight and got a big one within 20 minutes but tonight again she is upset and crying like she is pain, i just have a bad feeling it's something else but she can't tell me what. I'm really not sure what to do now and it's unsettling me as to what is wrong.

I just settled her again and it's now 12.30am and i've given her some panadol which the Dr said might help to relax her stomach muscles but I just cannot stand seeing her crying like that and it's in spurts, she will cry for 10, 20 or 30 minutes and then relax and go back to sleep so other than the constipation i don't know what else it could be as she is ok during the day. She is upset a little after her nap time so again it doesn't make sense, even the Dr said was unusual she was ok during the day and only getting upset at night.

Dr said if it was something more serious then she'd be getting worse and she'd be bad with it all day long. he said it could take 3 or more days to settle down but i don't think i can stand watching her cry for that much longer. No idea what to do.
