Has anyone had experience of this -good or bad? I've been told DD2 definitely needs it but she's only two and 2 months which seems really early to be deciding there's a problem. Part of me thinks we should wait a while and see how she gets on, part of me thinks we should be pushing for it ASAP. Would be great to hear what it's like from someone who's done it and in particular, whether it's enjoyable for the child, in which case we;d have nothing to lose
