Jenny, I have been the same way, but for a few days. LOL. Hubby is like, "what is wrong??? did I do something??" They don't get that answer, "I don't know what's wrong." LOL. Women...geez.
Hahahaha...it's cute in-utero. Past that - it's awful! I had to do something cruel and terrible to make my older one quit sucking his thumb (but HYSTERICAL story), and I can't get my younger one, who is 3, to stop sucking his fingers. He ***** his middle and ring fingers. Problem is, it pulls their teeth out...and in bad cases, their whole jaw can shift! So, be grateful!!! LOL. But I agree....it is adorable :-)
