Why do you think that the Bible exhorts the older women to train the younger women to love their children? You think that would come naturally but I guess it doesn't or the Bible wouldn't have to tell us this. The best way a mother can love her children is by loving their daddy.
Children love a secure home life. A mother and father who dearly love each other is the greatest gift you can give them. I think the second most important thing to give your children is discipline. If you teach them self-control, they will grow up to be disciplined adults and life is much easier that way.
Let them know at an early age who is boss. I see too many children running the households now and it isn't a good thing. Parents need to be parents, set good boundaries, and make sure the children live within those boundaries. Boundaries protect them and children like feeling protected.
Train up a child in the way they should go and when they grow up, they will not depart from it. {Proverbs 22:6} Train them to work hard. As soon as they can walk have them washing dishes with you and scrubbing the toilet. Sing as you do this and tell them how blessed you are to have dishes and a toilet to clean.
If you train them to be lazy and messy, they will grow up to be lazy and messy. Train them to be thankful and not complain. Train them to even get along with their siblings. Ken kept telling my children that they were best friends and that the Alexanders' didn't fight with each other and it worked! My children rarely fought.
Set high expectations for them. They will grow up and thank you for it. Most importantly, teach them about Jesus from the time they are little. Read them Bible stories, take them to church, and sing praise songs with them. This, I think, is loving your children.
