My daughter was the same way M. except for her it was vegetables. Now this year, she has started a fruit jag and won't touch the veggies. She's finally getting better about meat, but still doesn't eat the variety I would like to see yet. So I guess what I'm saying is it's completely normal.
The important thing for you to do is to keep presenting a variety of foods. That is the mantra I always tell myself. I decide when she eats and what to serve her. She decides what she will eat of what I serve her and how much she will eat. Sometimes she eats everything on her plate. Sometimes she will eat only one thing on her plate, but as long as I keep mixing things up and follow good eating habits myself, she will eventually even out.
My daughter is 3 now so it's not as bad as it use to be where she only eats one food group, but she still goes on jags where she seems to concentrate on 2 food groups at a time. My mom said I was the same way at that age and I know I grew up to eat from all the food groups so I have to trust in the process, and celebrate victories like the fact that she likes sauerkraut and broccoli. LOL!
Good luck!
