We have been using it since daughter was 2 months! With books under her to raise. She loves it and it beats lying on her back or sitting inclined. She's 5 months now and jumping like a maniac. Gets her fitter am sure. I agree: a godsend
My grandaughter, you've guessed it, Olivia, had one and was in it from being around 9 months old, she loved it and it kept her out of trouble. I think her mum used yo put it in it until she was around 2 or 3, she would sit in watching her favourite cartoons egg on the telly and used yo have her meals in it. It was a bloomin godsend.
These are awesome, but can easily be found £15-£25 second hand on FB or Gumtree, with parts that are easy to wash. Hope it helps somebody
