Not as old but my son had bad issues with gagging, vomited with solid foods until 10.5/11 months, hated spoons so was a bit stuck as couldn't eat finger foods without gagging/vomiting and wouldn't accept spoons of pureed/mashed food.
He was on 4 bottles and pretty much just one meal attempt until nearly 13 months. The health visitor said to cut milk and see. I didn't think this would help tbh but it actually did.
He also needed some more teeth as his gag reflex meant he needed mushier textures until 18 months or so.
We also got some shorter stubby spoons so he could self feed easier and he was actually happy to use these himself then also to be fed too later on (would accept the spoons being loaded to start). Teeth shouldn't be an issue now but gagging might be an issue if not used to the sensation so I would stick to softer textures initially.
He's my second and it was a shock after having my first fab eater.
It's hard but I would start reducing then cutting bottles. Also ditch the rule book, you need to foster a positive relationship with food so sweet stuff, processed stuff, if he will eat it then grand. I couldn't believe all I was basically feeding my 11 month old was puffs, rusks and fruit puree pouches, just to get him to eat anything. And sometimes I did have to stick a finger with the puree on into his mouth to get him to realise he might want to eat it 🙄
Then later once happy with that stuff I introduced more savoury stuff, mainly lower age range pouches. I found tortilla breads a good finger food as turn to mush in the mouth and can use as a vehicle for pouch contents.
He's nearly 2 now and I can't believe how stressed I was about his weaning this time last year. I hope you can say the same in 2027 🤞🏻
