DD 14 was always a 'gassy' baby, not colicy, just noisy.....if you know what I mean. She would complain when she got older of having a tummy ache, and then the following bathroom trips. (but not always after drinking milk, or ice cream, etc) And then she would be fine for quite a while, and then she would start having symptoms again. At 10, she was diagnosed with LI, but like I said, it comes and goes.When she is having problems,it will bother her for a few months or so. As long as she takes Lactaid tabs (or pills) before she indulges in ice cream, pizza, etc. she is usually okay. She usually does, even if it hasn't bothered her for a while, cause you never know........
