Child care

Megan • Trying for our third! First baby a miscarriage, chemical then rainbow. Second baby 9 months of trying 4 with clomid. Hoping for a quick easy pregnancy for #3
In a little less then 2 months I am going to have to leave my little man at a daycare and I am dreading the day! My sister and brother in law started taking their 9 mo old to daycare about 2 weeks ago and she has had a respirator infection and pink eye so far! I'm concerned about him getting sick being so young: ( plus he is very needy and cries when I put him down so I'm very concerned about this in a daycare siting!
I started looking on Craigslist for sitter ads but not knowing if anyone personally terrifies me and I don't know if I can be that trusting. I have a fear of someone shaking him or just neglecting him!
Such a hard decision to make : ( I really want to go part time at work but since I make pretty decent money it would really affect us and the crazy budgets and future plans my hubby had for us. So what to do?! 
Sorry for the long post I am just dreading when I have to go back to work 
And I have to include a pic!
