Well she gets herself hysterical when she's tired. And I'm not exaggerating, she really hates lying on her back but will not stay still. So I can't just put her on her tummy to sleep, she just crawls and stands and then gets very upset as she's so tired. She finally fell asleep. I think that the 5th time I strapped her in, with two pins so she can't sit up, roll over and escape. There is not much else I can do.
