Ds2 is 13 months and is not happy in his high chair, the tray dosnt come up against his tummy so all the food drops down between, it also dosnt pull up to the table so it feels like hes not quite involved when we are eating. Im looking at booster chairs so he can eat at the table with us but our table is pretty high and chairs low, even my 6 year old often feel more comfortable on his knees! is it possible to find a booster seat that will give good height?
