cloth balls (a set, in a bin), colors or ABC book, stuffies (turtle, dog, elephant, rocket ship, whatever), you can recycle his cute baby play clothes to soft blocks for stacking and throwing...
stacking rings, maybe felt foods (im waiting until nearly 2 to intro these)....
I Spy quilt, another beautiful blanket, special jammies, silly hats, a big fabric bucket or bin, stacking/ nesting boxes, a boy dolly, balloon cover/ball....
i love making toys for little kids

for something to make without sewing, you could woodburn blocks to make a personalized ABC set.
I made a felt Happy Birthday banner for my one year olds party, although I am sure we will use it for everyone's birthday now. And I used a white shirt and appliqued a big 1. I wish I had made a pocket for his 1 shirt; I will for his 2. I had to tie dye the shirt later because he stained it with cake icing! He loves his 1 shirt, but it is getting too small

Happy Birthday to your baby!
