My LO loves pushing things/pulling things. So something like this walker.
might be good.
He loves to empty things--so I fill his little basket with wash cloths, play silks (which are the best toy, ever!) and he empties it. Same with our basket of socks.
You can't go wrong with high quality blocks.
Mount a mirror on the wall where baby can see himself when he pulls to standing.
A soft ball to roll.
Things that make sound/music when you bang them (but not batteries). (a metal bowl and wooden egg are what we use).
A blanket to make a tent, or crawling tube.
If I were to buy toys now I would buy something he will play with forever, (play silks, blocks, walker, something like this
) or this
(my big kids still love this toy.
Otherwise I would just save the money to see what he is actually interested in. For some toddlers it is dolls, others vehicles, little kitchen, etc.
