My LO is starting to get bored and frustrated on her playmat, she much prefers to be sat up or standing (in her bumbo/on us/in her door bouncer). I'm debating buying her a jumperoo, but want to know what people think of them? Are they worth the money? It's going to be the most expensive "toy" type thing we've ever bought her so i'm a little uneasy about it incase she hates it Any thoughts / opinions welcome Oh, and what age can they be used up to realistically? Thanks !!!
