Suzi,
My husband has drove truck some. It's a decent living, but like anything else, there are good things and bad things about the profession. Go hang out at a truck stop lounge or restaurant and talk to the truckers and get some advise, too. I'm not sure how many companies would allow you to take your daughter with you?
Aside from that issue, I have a few other concerns...
First, if your daughter is going to be homeschooled by your (on the road) and your Mom (at home) and ride with you a week or 2 a month, when is she ever going to learn to interact with kids her own age?
Second, unless she is a bookworm, she may not enjoy going on long trips seatbelted in the passenger seat for 11 hrs a day. Granted, you'll stop for breaks to get fuel or eats or use the bathroom, but that is a long time for a child to be sitting. She will most likely become obese from the lack of activity. I do think you could be creative and find things she could do such as reading or crafts or crochet or something while she's sitting.
Third, do you want to be a trucker? Are you good at staying awake while you drive. Do you like being around others or wouldn't mind the isolation of being in a truck.
Do you have any experience driving big rigs or would you have to go to one of those driving schools and be committed to the company that put you thru school for your first 2 years? After that you'd have better options. You are right, in general, you'll only be home a day or so a week. Unless you look really hard and probably take a pay cut and just do route work where you are driving a delivery truck and go to work every morning and come home every evening. I don't know if you live in a big city or small town, but if you live in a big city, I'm sure you can some kind of regular job where you can be around your daughter and Mom.
Fourth, Is your mom willing to take care of your daughter AND homeschool her? I would guess there is a big difference in sending her to regular school and taking the responsibility of her education on your own shoulders?
Sounds like you've been doing day care for a while. Have you increased your rates at all? Are you registered or certified? Maybe you could look into doing the necessary things to become registered or certified and then you would have more leverage to increase rates or change how you get compensated?
How do you feel about everything? Are you wanting that drastic of a change? Or is it more a need for more income in today's cost of living? Haven't read the other posts yet, but hope they are helping you.
