I have a reptile rescue (as my name implies). I have, on several occasions had very very large snakes. We are the only group in this area that will take a giant snake with an attitude. We have a 9 month old son. now, before anyone freaks out. we also have a detached garage. There are snakes in the house. the biggest being an 11 ft burm. tame as a dead bird and blah blah blah. He's firmly kept behind shatterproof glass, 1 inch thick MDF board for the rest of the cage, the door has 2 of those gate latches that you see on the fences around pools and locks on the latches. Hes also well fed and quite happy. the majority of what we keep in the house are smaller things like RTB, JC, corns, etc... I will admit I have taken a picture with my son and snake. the snake was a 7 ft. red tail boa. put the snake around his waist and in his lap, snapped a pic and picked up the snake. My son has seen our big guys, i carry him to the garage and show him. ("see big snake", "see iguana" blah blah blah) I don't plan on taking a picture with my big guys and son for quite some time, eventually i will. he wont ever be playing with the snakes alone or anything stupid like that. I know from my experience that when we put the big guys on our shoulders that they do tighten up to hold on but they aren't trying to eat me. I don't think its a HUGE safety issue so long as there is supervision. we have made our trips to the liquer store and each snake has its own bottle of booz, just in case. (and yes, the booz are out of the kids reach too.) anyway, people are always asking me if its ok to have snakes and kids. for me, I say yes, if you take proper percautions. all my snakes are locked up unless they're being fed, cleaning cages, or if they're out for some sun. thats how i look at it, hope it helped....
