I am an IBCLC working for WIC part-time, per diem. In the fall I will be working 3 days per week, and I have the flexibility to switch days if one of my kids is off, or has something at school I want to go to. I also can pretty much take off as much time as I want (with my supervisor's approval) and just work more days on other weeks, so I can be off whenever my kids have vacations. The pay is not great, but DH is the main breadwinner and I was recently a SAHM, so we are used to living on just his income and mine is helping us save for college and do other things we couldn't quite manage before. Maybe when I feel ready to start my own business, I may start a private practice as a lactation consultant, but for now, I actually love working at an office and I am happy doing what I love all day long (helping moms and babies).
Dh has been doing a bit more around the house than before but I've also paid to have some extra help around the house because we are just not keeping up with it as well as when I was SAH.
