They can choke on anything. Of course, some little ones are better at taking small bites and swallowing. If your child is able to bit these baby bites, that should be fine, but I think it’s safest to watch your little one like a hawk when giving any solid at this age, and also learn how to deal with a choking baby (learn the manouvers for conscious choking and unconscious babies)
Should be OK as long as he takes small bites. Just sit beside your baby when he's eating solid food.
