We are having problems getting our 3 week old to sleep in the evening - she gets very unsettled around 7pm and then feeds on and off throughout the evening, getting cross and lifting her legs up and needs constant settling, this can go on for about 3/4 hours and then she will finally settle on my partner's chest. Her poos through the night are green as well. She is generally ok in the morning and her poos go back to yellow again for a couple of times. This is relatively new as she was pooing and feeding fine for the first couple of weeks. She is still putting on weight. They think she may be lactose intolerant and are now restricting dairy from my diet to see if that makes a difference. They say it could be colic/stomach bug/intolerance to something????
