So we've been doing EC with DS for about 5 months now. He's 7 months and we get 1 or more catches a day (depending on how many times I get him on the potty). He's just crawling, but lately he doesn't want to sit at all. If I try to sit him down (not just on the potty, but also in the highchair, in his carseat, on the ground, etc...) he stiffens up his legs so he can't sit.

His aversion to sitting is making it difficult to get him on the potty, and I'm thinking we need to take a break until he gets out of this stage. He's much too young to stand and pee, right? Did anyone else go through this? What did you do and when did your DS grow out of not wanting to sit?
