Hi everyone, I could do with a little help again. I have been combi feeding Zane since he was a week and a half as it seemed my breast milk was never enough for him - he would be latched on for hours and scream for more when taken off and put down to sleep. I introduced him to formula SMA gold Stage 1 and the hunger problem seemed to go - he seemed much more satisfied. I kept him on this milk and did more formula feeding as I could see him becoming more frustrated and hungry with breast milk until he started feeding almost 8oz each feed which was around every 2/3 hours again screaming for a feed as though we had never ever fed him! He could also get quite windy (not colicky) Just over a week ago we put him on the Cow and Gate milk for hungrier babies (Stage 2) and again for a couple of days he seemed more satisfied. He was going 4 hours between feeds and one night even went 5 hours. Over the last couple of days he has gone back to not being satistifed and very unsettled (struggling to sleep). He is still on the Cow and gate stage 2 and will drink between 4 and 5oz each feed. He will occassionally sleep (or settle while awake which takes ages) for about an hour or two and then screams for a feed. I'm not sure what to do really and could do with some advice. Do i keep him on hungry baby formula or change back to stage 1? Could his unsettled state be something other than the formula? A growth spurt??
