OK so my baby (5 1/2 months) started baby food at 3 months, per docs orders cause he's so big and advanced. When can I start slipping him more table food? I give him little tastes all the time and he loves it. I also let him gnaw on Vanilla Wafers when I'm sitting with him watching. I'm wanting to start giving him mashed potatoes or simple things like that fir when we go out to eat, so I can order him something. Just curious.
