If you're asking for gift ideas...DONT forget BOOKS!!! They need to learn to sit and focus. Some books on colors, numbers, BASIC/simple seek & find, texture books, board books of all kinds.
Manipulative games/stations that require a bit of thought process i.e. the triangle goes in the triangle hole, etc. Stimulate the MIND too.
We bought a battery operated "station" that had letters, phonics, simple words, etc. Start w/ the basic...letter recognition. When you press a certain letter, it will tell you what letter it is. Or...when they ask for the letter "A", you press it and it will say something like, "Good job", etc. Then, as they grow, they'll start to use the phonics, etc. There is a place for them to also learn to WRITE the letter. This is one of those "toys" that you'll use for the next 2-4 YEARS. Several modes to choose from for "play" depending on their age and stage of learning.
