Hi M., I'm kind of like you looking for answers, my grandson is 16 months and he has been walking for some time now (he was born with club feet which he had to wear a brace to help correct, so he still walks a bit wabbly) and he still puts everything in his mouth. Even the soft spongy toys he bites off pieces since he's got sharp teeth (3 on top, 4 on bottom) which concerns me if he swallows. I'm sweeping and vacuming everyday and I still don't know how or where he finds the things he puts in his mouth. A few times I caught him putting the whole cap from a jar of stage 3 baby food (which I did not realize his month was able to hold the entire thing) But we do still take him to the park and outside, we just have to watch him closely that he's not eating what he should not be. I wish you luck as you have 2..
