Azimuth does not know it, but he already has a small wire toy and a stacking ring toy. Please don't tell him and ruin the surprise. ;) Azimuth could really use a peg board and shape sorting toys. Also nesting things are good.
These are just a few ideas. Anything else you want to get him would be fine. Excluding guns and choking things. This kid loves board puzzles and momma likes him to have books. He wouldn't know if you got him hats, socks, bibs, or the like.
In future I will post more ideas as they come to me. Thank you for reading this.
