I'm worried that my daughter might be undernourished and lacking all the essential vitamins that she needs. My daughter was born weighing 7lbs 1oz and is now 8 months, but weighs only 15 lbs. I started her on solids just 1 week before she was 6 months, but she doesn't really like to eat. She barely eats one tablespoon of baby cereal. She's very picky most of the time and mostly only wants breast milk. Even though she seems to be OK, I'm concerned that she might be undernourished. I would really appreciate any advice.
