Chiming in with consensus, but yes, babies are easy - toddlers make you have to game after bedtime only.
Not in my experience. I'm sure this is a "it depends on the toddler."
The couple whose house we play in have a soon to be 4 year old. He's been at the gaming table since he was born.
He's usually at the gaming table, although he'll often wander off. He can be a distraction, but usually for one player or the other. Initially, he would spend most of the game on my lap. He needed his own dice and would ask when it was "his turn" to roll the dice. As long as we gave him a turn periodically (which had no connection to the game) he was fine.
Now, there are a few players that tend to deal with him. Everyone likes playing with him, and he'll wander off and play on his own some nights.
The biggest issue is usually bedtime, since we'll get together at 6pm and usually game until 11pm-1am. With that many "friends" visiting, getting him to go to bed is occasionally an issue.
It's not that there are disadvantages to this. However, the option would be to lose this couple and we don't to do that. Their house is, by far, the best place to play (they even have a second family room downstairs with an attached kitchen).
