Weaning - 9 months

Does anyone else just feel like they’ve gone backwards with weaning? My boy was so good on solids at 6/7 months and now just chucks everything, has a couple bites of something and throws it, won’t open his mouth to try things. I see other babies just smashing it and eating so much and cant help but feel a little disheartened. The only thing he will entertain at the moment is wotsits & potato waffles!!
