Re: What age did your kids learn how to rhyme?
Dd1 was my talker and loved anything to do with words. She was playing rhyming games before age 2.
Dd2 was between 4 and 5 before she cared about the concept. At 5 she's mostly pretty good with rhyming but still gets confused periodically.
Ds is about to turn 3 and doesn't talk well enough to do rhymes. If he gets the concept he hasn't indicated that he does to us.
