What's this about? Anxiety around #2 all of the sudden

Here's my big EC challenge. My little guy, almost 11months old will wake up from naps or in the morning and occasionally will have to have a BM. He hasn't been signalling as well for BMs -- though it was the place we started with for EC and he was most consistant about since we started pottying at 2 months old.

Lately it seems I can get half of it in the potty, usually the second half, but just now and one other time it was the first half. I got him to pee and poop and then he started to freak and wanted off the toilet. It seemed like he had to go more but he wanted to have nothing to do with it and then just went in his diaper while playing but didn't say anything about it.

He seemed freaked out by having to go so much or perhaps because we've been feeding him solids more it feels overwelming to him now that things are starting to firm up more. I'm still nursing him quite a lot so things are still on the softer side.
