This is how Serena:) does tummy time. Tummy time for Serena:) has become a wonderful affair with all three of us girls. Of course, Lina<3 thinks Serena:) is sleeping, and wants to sleep as well. Whatever Serena:) is doing, Lina<3 must join us, otherwise it will become a hissy fit. The unfortunate thing is that I am unable to do tummy time for too long with Serena:) as I am afraid that Lina<3 might hurt her in some way, by being too close to her, or by throwing toys at her. So Serena:) does tummy time several times a day, on the floor, and on the bed.
