I know, I know, usually people are asking about stopping biting!
Ds is 21 months, has most of his teeth through, and can chew well. But he cannot bite. So eg a sandwich, he just tries to cram it all in instead of taking a bite.
I cut up into finger food size pieces for ease as have to help dd1 as well (and often dd2) but I aware this is not really doin him any favours.
Fruit is the same - cut up into pieces he managed ok, but if I have him apple slices instead of apple pieces (for eg), or a whole banana, he would just try to shove the lot in.
I just tried with his sandwich, and cut it into strips instead of bits. I held the strip with him (so he couldn't cram it all in and choke), and he just couldn't bite it. On closer examination, he sticks his tongue out over his bottom teeth still, which is a big hindrance I guess!
Any ideas how to encourage biting?
