macgirlxo you will work it out, and give camming a go, it is obvious you are doing your research before. Being a mother and this type of work can go well together, as you can arrange more time with family. You should get some good tips here before you start and can get verified. 10+ hours will give you a great start if you and your husband can arrange that, work hard and you can cut it down later on.
I would guess that there are as many mothers who cam, as say singles who cam. Most mothers I know (those I know are mothers) time camming late night or during the day with children away, and I know of many who use a studio too (they trade income for convenience/ security?). Most do well enough out of camming to do it for longer than the average model, it seems to fit better than a 9-5 job. Finding time to sleep or real time for yourself and family will be your main problem, but that is motherhood.
As a member my only rule for models who are mothers, is not to breach their child's security. This is best done in two ways, protecting your own, and only general/ topical chat about children should the topic arise. Long term models in particular can get lazy with long term member friends. You need not hide the fact that you have family, but it is irrelevant to the work.
When a member asks about a models real life what he usually wants to know is where he/ she as a member fits in for you besides the token exchange, what is he/ she trading their free time and money for. Often too it is just chat, the member is simply entertaining themselves with such questions.
Maintain your privacy, but what you share must be close to honest/ honest, for the most part too much deception doesn't work too well on cam; it shows, members sense it.
Speak about what you are passionate about, for example if your child is ill and wont sleep, you 'can' say so but when conversation leads to the personal keep details to a minimum. For the example you may want to keep cam time short, your conversation would go towards quick spending, sympathy spending, some kind or reward for someone meeting targets early. Of course you could do that by simply saying that you want off cam fast tonight, then spend a while answering questions on why.
