my ds was bf until 6 months when i introduced a bottle of aptamil 1 every night. Then i switched to aptamil 3, it took me 3 months to realise it didnt suit him as he kept waking every night crying with tummy pain. Anyway i switched back to 1 as he digests it much better-however am worried about his iron intake as he hardly eats a thing and is not really putting on weight...can anyone advise what milk i should give him now that he is 12 months?
