Jolly Jumpers - How early?

Hi girls (and guys),

How early are you putting babies into Jolly Jumpers (jumper suspended from stand or doorframe)?

I have a 2 month old and obviously it's too early for her yet, but I was wondering at what age other moms and daddies were starting them.

Our baby girl is nearly six months old. She is very tall for her age and has been able to hold her head up from a very early age. We have just bought her one and she is loving it. I think as long as the baby has good control over it's head it will be fine. Just don't leave them in there for a long time. Bree is tired after about fifteen minutes. Hope this helps.

on the box it says from 4 months which is when I started to put Emma in hers but by 5 months she was rolling everywhere and was no longer interested.

I tried bayden at 4 mnths but his head got tired after like a minute. I left it until about 6mnth and tried him again. he knows how to use it and loves it for a bit. But he gets bored...id say 6mnths
