this kind of bottle rot isnt from daytime its from taking the juice to bed, which im guessing you have let go on. grandma must not care for your childs well being and id tell her so. i have kids and i know it is hard,,but you are the parent. if i seem tough well someone better, what is life going to be like when your child goes to school with no teeth? they will be made fun of, and its a situation that can easily be avoided. decay leads to other health problems, maybe everyone can listen to that.
Could you try putting water in the bottle at night instead of juice? I'm sure you little one won't be happy but maybe if it is presented as a compromise? Just an idea :) I don't have any children so I have NO idea what you are going through. Best of luck though :)
Well...as a mother of 2 grown kids, I can tell you it's not easy to raise them. But one thing I DO know is, ....that YOU have to stick to your guns. Do you have to take your children to their grandmas? Is she taking care of them during the day? If not, then I would tell her that either she listens to what you say, or you will not be able to bring them over anymore. If her feelings are hurt, that's too bad. She is not doing what is best for her grandchildren. It is easy as a grandparent to spoil the grandchildren. They don't have to live with them 24/7. But she is harming them instead of helping them.
I hope you listen to my advice. I have been kicking myself for not listening to my better judgment for that last 20 yrs! YOU are the mom, and you know what's best for your children...period. Grandma might be a little hurt, but she will get over it, hopefully.
