Hi we swapped Annabelle over to cows milk on her 1st birthday and to be honest it was the worst thing we could have done (for her) as she was constipated for 6 months there after, Eryn is 14 months and is still on formula and health officials actually recommend the use of formula milk until the age of 2, so after the problems we had with Annabelle we have decided to keep Eryn on it until then, rather expensive but rather the extra cost than the constipation. We did try her for a few days but she stopped sleeping, so we switched her back. I am sure Lewis will be fine though.
