G.R.
Hi R. - We went through that issue with our second floor windows. Proper window protection is not cheep but it is worth the life of my boys. I did research & found Guardian Angel Window Guards from OneStep Ahead. They fit great (if in doubt on the size get the larger one if you window is close to the cut off size. http://www.onestepahead.com/product/osa/464.html They were very easy to install and they don't look bad at all. There are very easy fire escape buttons built in so if an emergency came up you can get out fast (that part the kids do not know how to do because of their age). My kids are very adventurous and love to talk out the windows to people walking or our neighbor on the plow and I know they will not fall. I did read some of the other responses about using child gates but one problem I ran into with those just even being used in doorways my kids were smart enough to figure how they worked and could take them out or push & pull enough until they gave way, they even climbed over them. Depending on what your windows are made of the small locking clamps may not work efficiently. Using these Window Guards gives me a great peace of mind knowing that they are safe. Plus I can open the windows all the way and get the fresh air in without risking safety. Maybe an idea is to buy a proper window guard for your kid's bedroom and temporally use something else in the other areas until you have set aside the money for the others?? Good Luck & Take Care
