Nice to hear from you again Bc! How was your sojourn with your dad?
Ah, the nipple-fiddling thing.... DD also has wandering hands during BF - it drives me crackers sometimes. Especially if I have a spot on my chest (usually caused by little germy hands, I suspect!) which she then picks at and picks at so it takes ages to heal and go away.
Yes, don't they change a lot when they become toddlers, eh?! One friend said to me "Just as you're getting confident as a parent, the blighters go and change on you again..." I'm sure you'll soon feel you "know" him again once you get the hang of these new moods and behaviours.... 
"Dear Zoo" is a big favourite here, too.
I'm glad you found Playful Parenting useful, rainbow! You're right, when they're absorbed in something, it's best to just let them get on with it, provided it's nothing dangerous or liable to cause an unacceptable mess or breakage. (DD is currently opening and closing DVD boxes and taking the discs out and replacing them....they're DVDs we're not bothered about watching, I hasten to add!!)
Groo.... there was I thinking we'd cracked the overnight temperature thing and DD was hot and fidgety again last night. This time I changed her into the romper suit and gave her some ibuprofen (her canines are all making lumps on her gums, so that's probably a factor) and put her next to me in such a way that she could be latched on without too much of my body touching her (too hot) and finally she fell back to sleep.
Good news for Lily Allen. I bet she's paranoid as hell about it, though....
