playfelt was right on the mark. As for all the other children you are not giving them your attention all at the same time. With the age group you mentioned the children are probably playing on their own at times so that you can give one or two your attention while the others are playing. It's not an easy thing to let a little one cry when you are only eighteen. Sometimes letting them cry a bit teaches them to self sooth another way. Good luck with your little ones.
