my lo is about 15 months now and we are experiencing a few things that leads me to believe she may have a dairy allergy. as an infant she had dairy intolerance with my breastmilk (EBF) so i cut out all dairy and that seemed to solve the issue. when we started her on solids we slowly introduced dairy (cheese, yogurt etc) and she did well with it. but lately, she has started having belly aches when i put her to bed (squirms like her tummy hurts and clenches, plus i can hear gas) and cries out when she toots. she is a VERY wakeful sleeper (waking 4-5 times a night still) which i thought may be from the dairy. it seems to be more when she eats yogurt or ranch dressing, and not so much from mac and cheese (which i guess is because it is so processed!) twice this week she has tried ranch dressing and has a red rash immediately breakout around her mouth.
she doesnt throw up or have green poops that would indicate allergy, however she is quite fussy and just doesnt seem that comfortable. her poops are soft and not formed like they were a few months ago, they are more mushy?
does this sound like a dairy allergy or intolerance to those of you who have experience with it? if so, should i just cut out dairy all together from her diet or just the foods that seem to bother her? and how long does it take to see a difference? thanks!
