My daughter was 4 months old when we started putting her in the bouncer. She was still little for it so we had to put a blanket around her while she was in it. We started out putting her in it for about 5 minutes at a time and slower bumped up the time. She is 7 months old now and loves being in it!! She bounces like there is no tomorrow. She smiles and plays with the buttons and everything. I would say to just give him some time in and see what happens. I know that not all babies are into those toys. Plus sometimes if there are too many toys on it then they are overstimulated very quickly. That will make them not want to be in also. We got something that doesn't have a lot on it, but that we could add toys to. Hope this helps! Good luck!
