Sarah,
What formula are you on? Is it the first milk? or a hungrier milk?
My DD refused solids when I first started on them. I then stopped offering them and about 2 weeks later I tried again, and she took to them no problem. About 3 weeks ago, she started refusing them again, so I gave her some solids with a bit of texture to them, she wolfed it down. Now she is going through a phase, she will only purees again, anything with a tiny bit of lump she gags, or throws up.
