dd is one year old and she has something like 4-5 lower teeth and 4 upper teeth (all in the centre/front). she has been eating baby biscuits since about 6-7 months and seems fine with them, but started feeding her small slices of cheese recently, and she loved them so much that i may have given her too much and the problem is that she suddenly vomited and the shocking thing is the cheese bits were all exactly the same size as when i had fed them to her!!she hadnt bothered to chew them at all!!! when do they learn to chew and what should i do? what should i be feeding her? I'd thot at this stage that i'd no longer be feeding her mashed or pureed food .
