Hi J.,
First, I want to tell you about the nursing support group I am a member of. It is a online (yahoo) group called For Babies Sake. We also meet every Tuesday night in South Arlington at 7pm. The meetings are run by a fabulous lactation consultant, Mellanie. There is lots of breastfeeding support but also we all get advice and encouragement from each other on all kinds of parenting issues just like the one you've posted here.
Secondly, I want to tell you about an awesome website I found out about from the For Babies Sake group. It is www.kellymom.com. There is great info. on there on starting solids.
Thirdly, you sound just like me with my first. I was very concerned about getting my son to eat solids. Now I'm on my second child and have relaxed a lot and learned a lot more. Your son may simply not be ready for solids. I wouldn't force it. It is more trouble than it is worth at this point. He doesn't actually need anything other than your breastmilk to meet all his nutritional needs for the first 12 months. I would just occasionally offer foods to him. Eventually he will be interested and it won't be such a struggle. My daughter has almost completely skipped pureed baby foods and moved on to table foods by the time she was interested in solids.
Good luck!
