At what age did your child/ren get their first tooth? How did they act prior to the tooth appearing? And what did their gums look like while the tooth was emerging?

DS is 4 months corrected & I am sure he has a tooth on the way. He is screaming for no reason, feeding frequently, he has unusual sleep patterns & I can see a white spot on his gums. Is he too young to be teething? Also he is chewing anything he can get hold of.

I would love to hear your different experiences.

TIA
