my 15 week old ds has been going through periods during the day where he only seems happy if we walk him round - some friends have sworn a jumperoo is the answer but I have reservations - mainly the cost and also the size of the thing! We have plenty of space but to put it bluntly is pretty hideous to look at?! Also we have a baby bjorn bouncer where they didn't so they moved onto jumperoo after outgrowing bouncer which isn't an issue for us- is ds going to get anything more out of a jumperoo than his baby bjorn(that he loves)? I justified cost of baby bjorn in that would last ages so reluctant to buy another expensive thing.
