My baby is 6days old and although we had a slow start to breast feeding as he wouldn't latch on, we have now mastered it and he is feeding well. He has managed to regain his birth weight which is great news. Sadly he is really grizzly on evening between 9pm -12.30am and we can't figure out whether this is colic or due to being hungry. He starts getting crotchety and kicking his legs, it looks a bit like colic but is this too early? My husband is convinced he is hungry and that we should add in a bottle feed of formula at night but I'm not convinced its hunger. He has been feeding 2hourly but I have changed this to every 2 1/2 - 3hrs as his weight is so good and doesn't appear to require more. He has feeds of 30mins and then falls asleep. What does anyone suggest?
