Belly Baby???

Mummy read somewhere that it is important for me to have some "tummy" time for myself every day to strengthen my neck muscles, which will help me push up, roll over, sit up, and crawl. So Mummy put me on my tummy on the bed. Little does Mummy know that I already have had "tummy" time whenever she put me on my tummy onto her. I have already learnt to move my head and lift it side to side...
