I voted for a bit of both as well. I havent had bub yet but I think after about 18 months or when bub can communicate and walk, i would like a mixture of day care/ home care- grandparents and me staying at home.
I would hate to think i would be a stay at home Mum totally coz I got a uni degree to have personal fulfillment with a career and making a difference to the world and I think I would be a good role model for my bub if I am there for them when they need me (working school hours or only 3 days per week) and being a great Mum but also fulfilling my self needs of being Peita. I would hope this would give my bub time to get to know his/her grandparents and create a close relationship with them, plus going to daycare/homecare i think it helps them socially. I want my bub to not be afraid to go away from me and try new things. (this obviously wouldnt be at 1 1/2!)
But like I said I havent had Bubs yet so all this theory is wonderful and great, but until I have bub I probably shouldnt comment! :P
