How big is your lo?
I bought F a jumperoo today after many recommendations and in the hope it would exhaust him so he would sleep. He is only 15 weeks but has good neck control and is very long so thought he would be able use it but his feet are nowhere near the ground. I read posts online of people using it much earlier so can't really understand?! Going to have a look and make sure I have put the seat cover on properly but was wondering how everyone else managed.
