Baby seat for 3 months +

[Mymatty10]

Hi,

Could anyone recommend a baby seat for 3 months + hoping to last him until he is a toddler?
We bought a bean bag chair designed for babies but this was a mistake as he can now almost tip himself out of it. He's quite a long baby so the average bouncer will probably only last him a couple of weeks. Any ideas?

We had the fisher price infant to toddler rocker when dd1 was small and that lasted til she was 2, as she didn't want to lay down in a chair anymore, but size wise it was still okay.
