Montessori education is good for children and from one or other way its like getting your child to learn new things and get new friends

Its may be becz she loves children and she wants to spend time with them. Also its good for you if she is taking good care then sometimes you can finish your other work. Just think positively.

FB page for small child looks funny. However it looks too much, as if we are buying an Intellectual property for baby.

You can do that as small business and in fact in such situation people will be happy to make there loved one birthday party as great and memorable. If you can do that for them then yest you will get paid for that

I will not regret if I quit my job. Rather I would try to find an legitimate career option where I can take care of my family and still work from home to earn money.
