Got milk?

I've been conducting an experiment on Greta this past month and think I have finally determined that she has some degree of lactose intolerance. My dr.'s told me she didn't but looking back I know now that I didn't aswer the questions properly because I didn't know any different. They asked me if she was extra cranky or irritable during the day or after having milk. Well, she got milk first thing every morning and then was generally a grump bucket for the next few hours but that is how she always was so I didn't know any different. They asked what kind of diapers she had and again I didn't know any different and so didn't give them any info that might have been useful in helping me figure out what was wrong with her.

When we got back from Ontario I decided to switch her to lactose free milk just to see if I noticed any change. We noticed a huge change! She went from crying every night in the middle of the night, sometimes so bad she was inconsolable to not hearing a peep from her. She just seemed happier, not nearly as grumpy, just my smiley little girl. After a few weeks and a couple new teeth I decided to switch her back to regular milk just to see. Matt and I were ready to sell her the first day, she was MISERABLE! Nothing made her happy, she just cried and had 4-5 disgusting diapers a day until her poor bum was bright red.

We kept her on regular milk for 4 or 5 days because I didn't know if her body needed time to adjust back to having lactose but nothing seemed to be getting better. We are now back on lactose free or goat's milk and that seems to be working great. She can still eat cheese and yogurt but life is generally happier if we keep her off milk.

I could still be wrong since I don't have an official diagnosis but I feel much better with the road we are on now. Poor girl and our cruel experiment but hopefully she'll be better for it in the long run
