Baby falls asleep quickly to Baby TV.

Hi girls,
Do you guys have this too? I found it pretty strange.
Our third little girl, Jasmijn, is almost 4 months old now and she seems to get really calm from Baby TV.
She’s already a super easy baby on her own, but I’ve noticed that when she lies awake for a bit in her crib and looks around, if she watches cartoons and Baby TV with her sisters, she falls asleep right away.
I found it quite odd and wondered if more moms experience this with their babies?
Even when she’s in a little pain, the TV with cartoons and Baby TV is her comfort.
You can see directly that she calms down and falls asleep.
I didn’t want her in front of the TV at first, thought she was too young, but when she sat on her sisters’ laps, she naturally joined in watching.
And that’s when I discovered it.
