A few weeks back we were painting pictures and I showed her mine and she said "Wow, wow mumma. Really good job mumma!". Then again yesterday I made pancakes (my "weakest link" if you will) and was all bummed out about how they turned out, and when she tried hers she said "mmmmm, really good job mumma!".
I got all teared up - I guess I must be a doing an OK job with her, because she obviously learned this from me. Also they are honest at this age. So there's nothing like praise from a 2 year-old.
