I didn't know playing pretend would start so young. He's only 14 months! All day he has been running around with the lid of my hair mousse, pretending it is a cup. He'll take sips from it regularly, smacking his lips after. This isn't just a bring-to-the-lips-and-make-a-sipping-noise kind of drink. He throws his head back, lifting the cup, and chugs it!
I get to drink from the cup too! He holds it up to my lips, I take a "sip", then smack my lips, and sign and say "Thank you".
