Opinions on hiring help for stay-at-home parents

I get 12 months paid maternity leave with each pregnancy, but I still have to answer emails and such, so it's not like I'm not working at all. Husband is a stay-at-home dad, as both of us work from home. He recently brought up that we should get a nanny/housekeeper when the next one gets here and I don't know how I feel about that. We have friends who have nannies while the woman is stay-at-home and I think it's ridiculous that all they do is shop and socialize while another woman changes diapers, then they act like they take care of the family. One lady I know has a chef come into her home to cook for her and that seems like overkill.

I have no problem cleaning my own house and taking care of my little one (hubby plays with her most of the day) but we're buying a bigger house soon and I don't know if I'll still be able to take care of everything once I have 2 under a year. In a way I'm freaking out because I can't wait to get back to working but I also feel like I don't want to be away from them (breastfeeding for a year). 

Part of me is just venting here instead of telling hubby because I don't know how I feel - it changes every day. I don't know if it's lazy for me to allow a housekeeper or nanny to help out when the next one gets here. I can sorta justify it if we look at it like they're just an extra set of hands to run errands (grocery shopping, etc). If I was working away from home I wouldn't mind. It's just that I don't want to turn into one of those obnoxious housewives that have nothing to do besides attending charity events and work out at the gym. Does it seem crappy to hire help if you aren't working?
