my girls are weird. they sympathy teethe. when the baby is about to cut a tooth my 2 year old ends up annd congested with a runny nose thwn the baby starts drooling and gets a runny nose and congested... i always think omg they have a cold but nobody else in the house gets anything and my 8 year old is immunocompromised so youd assume if it was a cold hed get it too cuz hes always up in his baby sisters space and my 2yo touches everything.. then the baby cuts a tooth and all is right until the next one starts moving then both the girls start over again... its honestly the weirdest thing.
