My daughter is nearly 7 weeks and I need some advice please. After 3 weeks bresst feeding I put her on aptamil stage 1. She loved it and fed well. Then started with constipation and bad wind. Straining and in pain. She was sleeping well and going 4 hours but uncomfortable. I switched to aptamil comfort milk 4 days ago and I thinknits got worse. She did 1 massive green stinky poo after 48 hours but the past 2 days and nights gas been full of trapped wind and so upset. She us taking 6 oz of the milk and deeming at night up to 5 hours but now 5 mins after feeds she us crying and straining and drawing legs up. I know everyone says comfort milk is thicker but seems not much thicker. No have no issues with teets clogging or not mixing but it smells and tastes rank. I'm debating going back to aptsmil stage 1 cos she seems more upset if anything. She is also on omeprazole for reflux which does help and I've been giving her infracol but not sure if that is helping. Tried dentalux today but not sure what's best. Before the last 48 hours she was sleeping great up yo 5 hours in the night but particularly bad night last night. Hate seeing her in pain. My son had colic but was a few hours each night and I dont remember him being so constipated. Any help or advise would be greatly appreciated.
