Olivia can turn to the right side easily now, without any assistance. This is a new skill she learned recently, and she has been practicing it every day, some times when awake, sometimes when sleeping.
Everytime just before she wakes up, she will turn and lie on the stomach. She lifts her head, looks confused, then suck on the thumb, fall back to sleep.
She is a big girl now, can handle sleeping on the stomach!
