Anyone already experienced the language explosion? How many words do your tots have? Did it happen over night or was it a gradual increase in words?

My son has 7-8 words. It feels like pulling teeth to get him to say the words he knows. He was born at the end of August so maybe he's just not there yet?

He just had his 18 month checkup and the doctor wasn't worried, but I can't help but be a little anxious. When it comes to verbal communication, it seems like other kids his age are farther along. He does gesture and grunt/whine for things he wants.

He's hit all of his other milestones on time or early so this is a bit tough.
