My oldest Emmie never did, but our Izzy B. (14 months) loves to carry all her toys to her bed and pile them up, often times not leaving room for herself. Glad to know this is not unusual behavior for her!!! We have to check it out from time to time as she will pick up screws and assorted items she has "dug up" from some vast recesses of our home - we call her our little "pack rat".
