My daughter recently received the Melissa & Doug Reusable Sticker Pad as a take-home gift from a birthday party. She has played with it before when she was around 2 years old and she did love it then but she would put the stickers in her mouth then and I had to keep an eye on her and she didn't quite fully get the concept back then.
Now that she's 3 years old, she played with the stickers by herself for more than an hour and knowing my daughter, that's saying something. She picked each type of habitat and was happily removing the stickers and sticking them. The best thing is that the stickers are reusable and they only stick to the sheet which comes with the book - they are easily removable and repositioned. Also, this means less time spent cleaning up after her stickers for me.
I anticipate that she will get hours of enjoyment out of this reusable sticker pad.
I highly recommend this sticker pad for 3 year olds and it's a great gift idea.
