[blparent] walkers/ jumpers/ ????

[jan wright]

Hi All,
I have not thought about walkers or jumpers (they hang from the door
and your lo sits in it and jumps) for years. I would not have bought
such clunky things, but again, my sister found one for me. I thought
that I wouldn't use it, but, I don't know. As my little one seems to
like to jump lots, I am tempted.
But, I have some questions first.
1. we have the jumping thing, not the walker, but are there any
studies saying that this jumping thing is not good for a child's feet,
etc? And, weren't there studies saying that a walker actually "didn't"
help a child walk better )? (just in case my mother finds one at a
garage sale).
2. Because my sister got this jumping thing from a friend, I don't
have the documentation. so, at what age should a child be using it?
Should your child's knees be at a 90degree angle when sitting? What
are the other cautions, instructions, etc?. I'd look it up myself, but
I don't even know what that jumping thing is called. It hangs from a
door frame and has a bunjy cord in cased in plastic and then the seat.
thanks for any help.
