My DD's physio has warned me against using one but only because she is already behind in development and due to time in hospital as a baby and a chromosome deletion she is likely to struggle with her developmental milestones in the future so we don't need anything to hold her back more than needed.

I am a bit against walkers etc anyway so it didn't really bother me. When I did discuss it with the physio however she did say that if a baby is healthy and meeting milestones then a max of 10-15mins a day was fine.

My nephew practically lived in his jolly jumper and walker and he was walking independantly at 10 months and is a healthy active 10 year old now, hmm, I find that strange that I have seen that it did not 'harm' him yet I am still a bit unsure about them, I too just cannot see it being all that good for there back.

All that said, my DD was given one as a Xmas gift, she does enjoy it but I am very concious of her develpment so she gets one 10 minute bounce every 2 weeks (in between each physio appointment)

Good on you for informing others on something they may not have known or simply not have thought of
