hi S., i have used the crib tent 2 for my 2 youngest, i couldnt live without it, i love love love it. its not cruel or mean or anything, he sleeps well with it, and it keeps him safe. when he wakes up, he calls for me and i go get him. the thing is, my kids both used it from newborn, they never knew otherwise. your son is older, it might upset him to get that now. it wont keep him sleeping, but it will keep him from climbing out and hurting himself if (like me) you dont want him in a bed yet for whatever your reasons are. any chance he will go back to sleep if he sees he cant get out? you know your son, you are the only one who can even take a guess as to how he will react. i would buy it only if you would be able to return it if need be, its about $70. its called the crib tent 2, one step ahead.com will have it among others.
i also want to say i am so sorry about your mom. alzheimers is so very cruel. i hope you and yours can find some peace.
