You're asking Luke to lie still?

Adding another quick prayer request to yesterday's post. Our cardiologist's office doesn't perform sedated echo's unless they absolutely have to, so we need prayer for God to supernaturally keep Luke lying on his back for 30-40 minutes during the echo. Considering I have trouble keeping him on his back for 30-40 seconds to change his diaper, you can imagine I'm a little unsure how this is going to work. I'll be bringing movies, bubbles and snacks, and the front office ladies help out as well with entertainment, so hopefully we'll get good pictures!
