Hi, My baby is 8 weeks today and is fully formula fed, i originally started her on A2 platinum as recommended by a friend of mine. I have just recently changed to S26 gold comfort as i was finding she was hysterical after every feed and was climbing around in pain. Her pain has settled to only a few of her feeds (she settles fine overnight), however she is still quite unsettled during the day, she will usually cry herself in-between her afternoon feeds, i think its because she is trying to hard to poo. I know that formula makes their poos more firm but it is quite hard for her to pass (she will eventually pass it) Can anybody help me with some suggestions of what formulas have worked the best for them with similar situations. Thanks!
