Why do cribs have bumpers?

We'll I think Lexi and I have figured out a few of the reasons. I personally used to think they were all just for show. Of course this was when Lex was in the blob stage (ya know leave them anywhere and when you return their in the exact same position. Not to say that I would just leave Lexi hanging around at a bus stop by herself. Of course being a good mother I would leave Toots with her.....Okay sorry getting off topic...) Okay on to the reasons....

#1 For when baby has woken up and somehow placed their neck and head at such an odd angle that their head is smashed up against the bumper.

#2 To provide baby with a good sucking session

#3 To entertain baby with its bright color. (Yellow is a big favorite of Lexi's)

#4 For when baby starts to sit up, but has had a little something extra in their milk so their feeling a little tipsy.

#5 For when they become little rollie pollie's and need a barrier to stop them.

#6 Lastly to keep their feet from getting stuck between the slats when they start going kick crazy.

I literally caught her mid roll :)
