BFing and solids (repost from 3-6 month board)

coromble

First of all, if you BF, did you introduce solids at 4 months or 6 months?  My LO is 3 months, so I'm trying to decide...

A friend who is very pro-BFing said it was better to wait until 6 months.  I want to BF, but have had every issue under the sun and just when I thought things were getting better...I got mastitis a couple days ago  I'm just wondering if I start LO on solids at 4 months if she will BF a little less frequently, therefore allowing to nurse longer.  Otherwise, if I can make it to 6 months, I might just call it quits after that.

I'd love to make it to a year, but I just don't know...any thoughts?
