18 month old TOO calm?

Witwicky

I feel crazy for posting this but I'm a worrier.

Does anyone have an 18 month old LO who calmly lays and watches TV with them? My daughter does and is doing it now, after dinner. My other daughter is 100mph 100% of the time so it's different to me and I'm wondering if my youngest is TOO calm?

I'm enjoying the snuggles but am wondering if this is typical.
