My DC who is almost 10 months had his 9-12 month check with the HV and HV said that he should be pulling himself up on furniture, gliding and bending down to reach a toy. He is meeting all other milestones, just not this one yet. HV has said Jumperoo probably to blame and is holding him back. I usually put him in there for about 20/30 minutes a day. Has anyone found anything similar if they've used a jumperoo or is it just the fact that babies develop at different paces?
