OP, you wouldn't even ask the question if you were a man. Let DH do all of the home stuff and go out as make as much money as you can as fast as you can so you can step back a bit when the kids are teenagers. Don't be afraid to "go for the gold".
Such bad advice. These partnerships are transitory and really difficult to sustain. I am the woman who was a partner and left to go in-house down thread. I really cannot tell you how incompatible big law is with being a present parent and partner. I worked with regulatory attorneys and was at one of the biggest shops in DC and saw that it wasn't too different. You have to either generate business or get a partner to feed you (as a partner which is difficult because you are too expensive -- this include counsel positions).
I really recommend the OP look in house if there is a regulatory need on a client basis. You'll make more and get the hours of a government job.
Also, OP's DH is a SAHD. I cannot tell you how many women I worked with at big law who are paying support/alimony to their husbands who stayed home and resented the demands of the job on their wives. The worst case scenario is ugly.
