7 month old baby, EBF. Started weaning at 6 months with mostly finger foods, sometimes using a spoon (he liked feeding himself using a spoon too) for stuff like yoghurt, soft cheese, porridge. He took to it well, and from the nappies was clearly swallowing stuff. Chewing well, some gagging but never longer than a second. Didn't like everything but liked a decent range.
For the past 2 weeks he's barely had anything. This coincides with two top teeth breaking through the gum. Before they broke through we had a few days of not breastfeeding well. Since then he is gnawing and biting everything except food... finger food he brings to his mouth and then recoils as soon as he tastes it. If he does eventually take a bite, he leaves it to sit in his mouth for ages (5 minutes +) before letting it fall out or swallowing it with dramatic facial expression and minor gagging.
Does this sound teething related? or something more sensory? I'm worried we've traumatised him but there haven't been any incidents. It's the same with finger food/spoon fed by himself/spoonfed by us. The only thing he wants is water (and breastfeeding). Any advice other than just waiting?
