For the last 2 yrs, every time Lucy held that bunny her thumb went in her mouth. I loved it. Oh, so cute. A few weeks ago I noticed she wasn't sucking her thumb anymore so I started paying more attention. I haven't seen her suck it for a loooong time. I think she's done. Everyone I mention it to says, "Oh, that's great!". It just makes me sad. My baby is growing up too fast.
