My lb is 8 weeks old ive had a bit of trouble with his milk i started him on cow and gate but he was always fussing and only went a hour between bottles so tried him on the hungry milk but he cried constantly so changed milk completely to aptamil he is happier now but still eating 4-5oz every hour/hour n a half so should i try him on the aptamil hungry milk? Ive got a 9yr old with a disability to look after as well so getting longer between feeds would really help he is a big boy he was 14lb2 last time he was weighed at 5 weeks ive tried to get him to take more at a time but he just throws it back up
