Going to see someone postpartum

I went to see my sister today, after she had her second child, and second c-section. Immediately, when I walked in, everyone was hovered over the baby and asking the father how the baby was, how much she's been crying and so on. Now, I understand, you're going to see the baby. BUT, can't you at least ask the mother how she's doing, if she needs anything, if she wants anything, if you need to leave so she can rest, etc.
