My daughter will be 3 in July and she's very chatty! It's been so entertaining to watch her learn language and see the funny mistakes she's made along the way. A few days ago we were walking to the playground and she said "mom will you carry me, I'm getting a little busy", I was puzzled for a moment before I realized she was telling me she was tired. I gave her the right word and we continued on. Yesterday we were out walking again and this time she told my husband that she was "getting a little busy" once I explained what she meant, he told her that she was actually getting a little tired - she agreed that she was a little tired (not busy). Most toddlers learn language so effortlessly that the mistakes are here today and gone tomorrow, it really is amazing to watch as their little brains learn. I'm sure when I take my daughter out for a walk again this week, she'll ask me to carry her because she's tired...perhaps what I should really be thinking about is investing in a double stroller so that I'm not pushing a stroller and carrying a toddler!
