In less than two weeks she’s returning to work, which means she’ll have some type of child care.

She’ll be at work having time for you while right now she’s likely with a baby all day (we don’t know what kind of baby she has either, easy going or problematic). I assume her husband works.

You had that concern before that how will she be ready then if she’s not ready now. Now she is providing full time child care. When she returns to work she’ll be be leaving the house and won’t be taking care of a baby all day.

Maybe you could focus on the fact that it’s not that she doesn’t care now so how will she care later. It’s just that her life is different now but it will be changing when she returns to work. She’ll be out of the house.
