DD has a blue fisher price seahorse that she loves and has affectionately named "Acorn". She turns it on every night when she's falling asleep, and she usually has it on in the morning when she first wakes up too. I would like to get something like that for DS (who is due to arrive any day), but seeing as DD already has the blue one, and I don't want them to have the exact same toy to get confused.. what do I do? Get him a pink one? Is there something similar to the seahorse but different enough?
