Thank you for the feedback -it’s very helpful & reassuring to get info from all of you guys.  Our appointment is tomorrow am, and except for not liking to be restrained, I think he’ll be fine.  There has been no bleeding whatsoever, luckily -and I agree, I am thankful it’s his baby teeth -and really, I’m surprised it didn’t happen sooner just with all the stuff he’s always putting in his mouth :)  thanks again!
