Dear S.,
I'm a single mom (now), my daughter is 8 yers old. When I had my daughter, we (my husband and I) allready were not in the best times of our life. But he supportet me and my daughter for life nessecities for 6 months. It means, room & board. We survived. I did not work. I started to work part time taking care of elderly couple, when my daughter was 5 months old. Most of the time I went to work with my daughter, because I still was breastfeeding her. They were a wonderful sweedish couple, they allowed my to have my time to take care of my daughter. I wish I had more things to buy for myself, but it was okay. Why I'm telling you this? Because those first yers is the most important thing in your to be son or daughter's life, and I would not advise you for at least the first year to have a babysitter. I assume, you are not a single mom, and your husband is waiting for that new life to come as anxious as you do. And I assume, he wouldn't mind, if you stay home for at least a year with your baby. Even with a small salary, you will by able to afford it, I'm sure. And those years will never return...
That would be my advise to you. If you still want to look for babysitter, I think the best idea is to ask your friends or aquintainces. Dont be affraid of agencies, too, because they also ask for refferences and usualy screen their workers, especialy babysitters. Otherwise, you will be (maybe, you are?) a perfectionist, but this life isn't... unfortunately. I am, sometimes, and I know, is hard...
My best wishes for you and you baby. It is not nessesery to respond, but if you wish, you are very welcome.
N.
