My son used an FP rainforest jumperoo at the infant care, a Lucky Baby sit-in walker, and a Playskool push walker.
In my opinion, the Playskool push walker was the best investment. My son walks now and the walker can be converted to a sit-on car which he is now exploring to use.
The jumperoo, he got bored of it after 3 mths. The sit-in walker, he was bored of it after 1 month.
