DS is picking up, licking and sucking some of the things I've given him - apple slices, pear slices, oat cookies, rice cakes, etc. He has now also developed a new skill of 'biting' off bits (doesn't have any teeth yet), but the attempt to swallow them, or just move them with his tongue, invariable makes him throw up. Sometimes it's only a small posset, but often more. He now vomits at every meal of solids.
Is this normal? If you have experience of this, how long did it take your DCs to get over this stage and to learn to swallow without throwing up? Did you do anything to help them learn faster?
Any stories or advice would be gratefully received. I'm starting to worry that he leaves the table with less food in his belly than when he started...
