Usborne has some of their Spanish children's books on 70% clearance. I got one in my last order called "Mascotas." It's a GREAT book and was $2.99. Each page has a little puzzle for the baby to put together and something to "touch" (fuzzy ears, etc.). If you're interested in seeing the Spanish flyer, click here.
You can then order the items at my page here.
There is a ton of research that says teaching your child another language as early as possible will help them acquire it easier. This includes just seeing the words (if you don't know how to correctly pronounce them). Every little bit helps prepare them for future learning (belive me!!).
