@Liv looking at his mouth I can't see anything currently. There is definitely a chance though, he is missing a handful of teeth still. But he hasn't really seemed teething fussy either.
My son is 16m and doesn’t want to eat on his own anymore. He wants my food from my plate. Not ideal but it’s working for us and it made him much more interested in restaurants. It also helped us to change our eating habits. Have you tried that?
2 year molars ?
Is there any chance he teething or he coming down with something ? As my son was the same last week
