You know, just when you think you know the rules to the game, everything changes! I have always felt this was almost a mantra during my child rearing years.
My 2 boys, now ages 27 and 17, hated their cribs. The oldest shook his apart! The youngest just cried, like you said, for hours and hours. Of course that benefited nobody, so I would take him out and rock him until we both fell asleep. And woke in the morning in the rocking chair, again not so good.
My daughter, age 8 now, would NOT sleep with me. I wanted her to as I was breast feeding and she was eating alot and often! So I would put her in her crib, and she would sleep for her 2 hours, then wake for another feeding. Again, and again ,and again....:)
I truly think that once kids get a taste of an interrupted sleep cycle, and they are old enough to get it, they really latch onto it. I think it's a control issue, partly. Also, wouldn't you rather snuggle up with someone that you know is just around the corner rather than sleep alone, at least sometimes?
So here is how we dealt with it. And I should tell you first that eventually, our daughter found out that she DID like to sleep with mom and dad after all...We let them sleep with us. Oh my, the people that we told were mostly horrified. We were spoiling them horribly, we were messing them up for life. They would never be able to separate from us......
Facts: All 3 kids are very well adjusted, stable, and independent souls. Yes, we had nights that we did want some alone time that we just didn't get. And for awhile there you would have thought the bathroom was our bedroom. But you know what? They are only little once. They needed and wanted us and we were there. And they still know that we are, although we have our bed back! And once in awhile the youngest (8), will crawl in bed for a few minutes, but then she goes back to her bed, usually quite quickly. She just wants reassurance now and then.
I say do what works for you. There isn't a right or wrong answer. We didn't get manuals when our kids were born, thank God. If it feels right, it probably is. And if you don't want them in your bed, that's ok too. You will just have to work out a plan.
I know someone that did the blow up mattress deal. She put the mattress next to her and her husbands bed and told her child he could sleep next to them, but had to stay on the mattress. Then they moved in closer to his room however often. Until it was in his room. And then he eventually got into his bed. This seems arduous to me, but hey, if it worked for them, it worked for them.
I just don't believe in letting them cry for hours. I think 20 minutes is enough, even more than enough. Personally, I love that my child loves me so much that she wants to be with me. I also love knowing that my kids grew up secure and confident, and really cool people.
Have fun and remember, the most important thing is that everyone is getting enough sleep! PS. My 27 and 17 year olds don't sleep with us anymore! (hehe)
