My daughter really started playing up when she was about 3 weeks old, she wouldn't settle, her crying was awful,and she was constantly sick, i was also getting upset as she was my first and i couldn't work out why she was being this waymi felt useless and with lack of sleep was grumpy and very tearful!
After a few weeks she got prescribed DOMPERIDONE and RANTIDINE all though she's still being sick alot she's now a happy baby and gaining weight VERY well!!
I would recommend these medicines!!
