I know it sounds elementary but I remember wondering…. how will we know when he’s outgrown these things; all these “devices” we’ve blown our wad on….his swing, this bouncer, this Bumbo, this chair, etc… Well, I guess it’s pretty easy to find out…
Looks funny here but can be dangerous so keep your eyes on that little monster. I had him in the swing, totally strapped in, but he managed to get folded over the back with his head about to hit the ground. He also fell over sideways on the ground in his little camp chair. Funny to watch but not very safe. So, suck it up, realize your money was “well” spent, and put that no-longer-useful device in the garage, waiting for the next one. 
I was trying to find more information on this topic yesterday when I found your really fascinating post…thanks a ton for sharing your thoughts. I will surely be keeping an eye on your blog and visiting again to read new articles.BTW how long have you been keeping a blog?
