Rattles, teethers and links

My baby is almost 5 months (loves her HugaMonkey, BTW) and has started to find a REAL interest in toys. I have a bunch of toys left over from my 4-year-old and she is really not interested in the kind of toys he was interested in. Isn't that so strange? (Insert "not really, lady" comment here.) But my little girl wants hard rattles, circle links and plastic keys. She really doesn't care for squishy or fabric toys, which is what my little boy totally preferred. 

So I'm on the hunt for new toys (a favorite chore of mine). There are some great choices at just the local grocery store. There are these great plastic Gerber phones and plastic dumbell-weight-looking rattles. I have also found great options on Amazon like this and this. 

What about you? What did your just-starting-to-love-toys baby like to hold, eat and shake?
