Advice on finger foods please

[familygirl30]

Hi ladies my son is 9 months and has one tooth so far,my worry is that with finger foods like toast he just shoves the whole piece ( finger size) in his mouth so I started breakin it in to smaller sizes pieces for him to use pincer grip which he's fine with he also does the same with rice cakes!I tried him with the Heinz baby biscuits and he sucked big piece of and struggled with it so stopped them for a bit.Hes fine with the carrot sticks( like big wositts) and also fine with other smaller things like grated cheese,scrambled egg, raspberries,just seems to b the harder things
