I also bought a few used books on Amazon for $.01. Yes, you read that right: one cent (+$3.99 shipping, but still...). One of them arrived last week and I have really enjoyed reading it. "Baby Days: Activities, Ideas, and Games for Enjoying Daily Life with a Child Under Three" is full of activities divided up by time of day and age of baby. It's funny that I need a book to remind me how fun it is for Sweet Pea to play with a box of tissues, but I do! I get so caught up in the day-to-day routine of taking care of her and myself and I forget all the other things we could be doing. Anyway, I am loving the book. When the others arrive I'll let you know if they are worthwhile.
In the meantime, check out my Activities for Toddlers Pinterest page. There are so many free ideas on the internet from lots creative moms that it's actually a bit overwhelming!
