Jen, my tea sister!
I am so, so, so sorry to hear that your son was bitten. Regardless of the fact that many children bite, it is still VERY upsetting.
Both DH and I had to work for awhile when our oldest was 2. DH had accepted a position that paid less than his previous one, so that he could gain more experience in his field. So I worked full-time for 9 months, leaving our son at a reputable school, known for gentle discipline and child-led activities.
One day, I went to pick up my precious boy and he was very quiet and whimpering, and I was shocked to see human bites up and down his arm, at least 8 of them! I questioned his "teacher", and she said she knew nothing of it. She added that she had never heard him cry. (he had broken skin which bruised as well) I looked her right in the eyes and said "I don't believe you." I went to the director of the school, who said that an accident report would be filled out and should have already been filled out.
Basically, at that point, I said I would be in touch, I needed to go talk to my husband...
There is more to the story, but to keep it short, I will tell you, my husband's employers allowed him to take a leave of absence. I quit my job. We took a month and visited family, while we re-grouped to work towards a better solution for our child and our little family.
DH went back to his job and I started a new one, yes, you guessed it, in child care. It was part-time, but we managed. And I took care of 4 year olds, but my child stayed with me all the while, when he was 2, 3 AND 4. He adapted well, and was like my assistant. I spent my entire 2nd pregnancy being loved on by the sweetest preschoolers ever. With the blessing of their parents, I helped to educate them about pregnancy and babies, in a natural way, when they asked questions. They were wonderful children, I often think of them and wonder about how they are now.
When my 2nd son was just 6 weeks old, my DH got his break, and we moved to a different state. From then on I could simply concentrate on my family.
As many of you know, my oldest is 20. I have never regretted the choice to quit a good-paying job to make sure he was cared for.
Hugs to you, Jen. I hope you can find a solution that works for you and your family.
