Mother Hen hammer toy

Now that I have to finally admit to myself that the baby is growing and less interested in teething toys as she is her big sister's stuff, I'm looking for toys that will help develop motors skills and hand-eye coordination. I know that she'd totally dig this hammering toy in a few months: use the wooden chick mallet to hammer the eggs through the holes and through the mother hen. Now, like with any toy, I can totally see the kid using the mallet on her sister instead of the eggs (because of course, she's got to play with all the baby toys we well as her own). Did I tell you guys how, when the baby was playing with a small plastic toy kitchen, the kid took the refrigerator door in one hand and the baby's head in the other, and bonked the 2 together? Ugh!
