Sasha: like someone said, i dont think they cause any problems unless you leave them in there for hours at a time, We have a jolly jumper, G loves it but only goes in it for about ten mins at a time normally once a day but we have some days where we dont use it.
I used a baby bjorn (sp) for the first few months then read that they were bad for the spine, sometimes it was the only place she would be happy and wed walk for an hour. Dont use it much now after i read that though, only when we are getting the bus somewhere.
Your a great mum and im sure you havent done any damage. But big hugs :hug: i know how you feel!!
