Just a vent post

So my oldest daughters father had a baby in Feb 19. my daughter has no bond with her brother. They are always asking her what can her sister (my June baby) can do. She has told them that she can drink out of a straw or a cup. They argued with her that a baby her age shouldn’t be able to do that yet, she was 11 months when she told them this. She just came back from visiting them again and told them her sister can talk. Again they argued with her babies her age can’t say words. Their son is what 17 months old still drinking from a bottle, can’t say mama dada or any other words. He can walk any that’s about it. And they moved to Arizona and argue with me it would be better for her? They clearly have no clue how to raise a child when this other mom still had her 7 year old drinking from a sippy cup because she isn’t old enough to drink out of a cup either! Ugh that is all. Along with all our babies must be geniuses because according to them none of them should be doing any of the things they do!
