Aw, that is so cute with the alien baby. I have a 3 year old grand-daughter, and she comes up with the strangest and funniest things too.
You sound like you are doing well. Don't let the R between S3 and H become too stressful for you now ... cross that bridge when you get to it. As you say, he only wants to be a dad when it suits him, so you'll know (probably) when those times will be, then be able to prepare S3. Just a thought.
Take care.
