This post comes at a perfect timing. My mom currently watches DS and his cousin (15 and 13 months respectively). My mom is in her 60's and by the time my #2 comes along, I think 3 kids will be just too much for her. So, my plan is to put DS in daycare and have my mom watch #2. Luckily, I do plan to take off one year off work.
I started looking into daycares already (mainly on-line) and haven't toured any yet. I totally agree by going with your gut feeling. My older sister worked at a pre-school and she would also tell me some stories about some of the teachers. It is true, some will act a certain way or have everything polished if they know you are coming.
