So I've never had a baby before (shocking I know) and with all kinds of stuff that could happen, I just have no idea how long I'll be out when we have our baby. It's still two months away but I imagine I'll at least be missing for a few weeks at minimum. I honestly don't foresee just being done playing WoW, but I have also seen it happen to most of the people I know that had a baby.
My current plan is to miss 2-3 weeks and then be back to raiding 3 days a week. That said, I imagine April is right when the hard bosses will be, so I would think loot council should prioritize most people over me.
