gums are as strong as teeth, have you ever been gummed by a baby, it hurts, lol........my 4 kids all got their 1st tooth at 13 months but they were off of pureed foods by 10 months......at 10 months they ate all table food that i made for my husband & i........everything is just smaller & softer.......you don't need to make him his own food anymore he just needs to get used to the foods you eat......maybe you are not steaming your veggies long enough, pampered chef has an awesome steaming container that goes right into the microwave, even though my kids are older this thing is my best friend still, you can make veggies as soft or tender as you desire or use it to just heat up food.........beef is a little harder for kids to chew so make sure that its very tender & juicy like a pot roast & pour the juices over it.....same thing with chicken just make sure its tender & not dry, you can even boil chicken, thats right just through chicken in a pot of water & let it boil (like a hot dog)......your son can also eat ham & cheese sandwiches cut up into little tiny squares that he can pick up with his fingers......make him some elbow pasta or rice mixed with peas & chicken & put a little butter & parmesan cheese..........make carrots super tender & cut up very small, my kids loved black beans cold or warm........at 1 yr my kids loved meatloaf, enchiladas, beef stew, chicken & rice soup, stuffing, chicken with pesto sauce, cheese tortellini with alfredo sauce.....well hope i gave you some ideas
