HI,

My niece didn't crawl for a long time, and when she did she bum shuffled, probably around the age of your bub. She didn't role much either.

RE food, i'm not sure. Find a favourite and focus on it?? eg if they eat fine pureed food, sneak in a couple of lumps. or go strait to finger foods. as naughty as this sounds my ds loves hot chips.

but if you want a healthier option, have you tried rockmelon. I have found it is the best texture/temperature for when ds is teething. nice and cool on the gums not too hard or soft, he can hold it in his hand, and who cares if they actually eat it or not, it's all about trying. and sometimes the food tastes better off mums plate, not sure why, just seems to.
