how can I be know that i can be a good mother?

Experience is laways the best teacher. One would never know how you will become a good mother if you won't experience becoming a mom. :)

I have raised my children and one thing I have learned, you will always have doubts. There is nothing you can do about it. I suppose you do need to remember that if you love your child, give them the attention the need, teach them everything you know about right and wrong, give them confidence and raise their self-esteem, guide them to the best of your abilities, make sure they are well taken care of medically and you do everything you can to make sure that the are happy, then you can be sure you will be a good mom. Another couple of things, listen to your children and respect them. In return, they might (just might) listen and respect you.

Total care must be provided to your kids,be a good provider,a good friend to them.talk to them always and give good advice,do not spoil them instead try to make them a better person as they grow old.being a mother is not an easy task,you have to sacrifice for it.
