My son has been colic since 3 weeks old. He is now almost 9 months and most of his colic is gone except for night time gas. He has drank Alimentum for most his 9 months but I know at a year we will switch him to regular milk. He is lactose and struggles still with any new foods we introduce. I will try him on regular milk @ 12 months but very skeptical that it will not mess with his stomach. Anyone know of a good soy/lactose milk with lots of nutrients incase I have to go down that road?
