Girls, hi ? This is just a nightmare? teeth, it's some kind of horror. Since yesterday, I feel like my son was swapped. My super calm son, became aggressive and crying. Doesn't let me do anything, he cries. Throws toys, hard tantrum. First time writing such tears in a flood. Never allowed him to get to the tantrum this bad. And here, tears flow by themselves. So sad ? Yesterday there were holes in his gums, today already white tooth poking out. Will it still be long before the white start of the tooth shows up?
