Agreed. Option #3. I think it's good you're thinking about it like you are, but you have to do the best thing for yourself and your family. Sounds like you're a solid, thoughtful employee so you're really not doing anything wrong here. I have similar internal struggles with my job (different situations, I just mean the guilt). LillyTame is right though, they'll be ok when you have to take your leave, and then you'll come back as an awesome employee maybe even making more money than now! That is so great to have daycare provided at your office, by the way.
