I have 3 kids. My first got her first two teeth through the gums at 3 months. My son got two teeth through the gums at 2 1/2 months. My third just got one tooth through the gums at 6 months and has another on the way.
My LO is 5 months tomorrow and it's hitting him hard right now he's not sleeping soundly. I can see the teeth under the gum. I hope they pop through soon!
