I’m not a rabbi, but off hand I can think of a bunch of factors that would make it not a problem:
1) If he’s sleeping when it happens, it’s probably Mis’asek (or maybe less)
2) It’s a Melocho She’eina Tzricha L’gufa
3) It’s probably considered Kil’achar Yad
4) Is Mocheik even a problem with pictures (not words)?
I’m sure there’s more…
