Congratulations, Lori! You will soon be adding a fun little boy to your original three furry children!! They will have a blast together! As for the bumper pads... I've used them with all three of my children. As long as they tie (on the outside of the crib) along the top and the bottom, you should be fine. I have never had a problem with the kids getting tangled in them or anything like that. They have been a help to their little heads when I check on them and their head is against the rail of the crib. It's got to feel better to have your head against the bumper pad than against the hard rail. I used them until I took them out of the crib at two years old. I think you'll be just fine!! Best of luck with the delivery!!
