A question for the mommy's Re: Solid foods?

So, my little girl is now 5 and a half months old and I started rice cereal at 4 months with no luck. Now I have tried the Gerber 1st foods (peas, carrots, squash, etc.) thinking that would motivate her somewhat... no luck. Is eating solids just one of those things that in some cases, a baby grows to love over time? Any other moms having trouble?
