I saw the other sleep-training thread but didn't want to hijack it with my question ...
My twins are six months. One of them is a great sleeper--almost always goes down easily, often sleeps until 4am before a feeding.
The other will only sleep in my arms or next to me in bed at night. This situation came about because he had reflux and I didn't want to let him cry. I think he's ready for sleep training, but I'm worried about disrupting his brother's good sleep habits. Should I sleep train him in a pack'n'play in our room, or just go ahead and put him in the bedroom with his brother? (His brother is very sensitive to sound and will definitely start screaming if the other one cries at all.)
Re: Another sleep-training question
I have the same thing, one great sleeper and one who would sleep with me until she goes to college. We sleep trained and it went pretty good. My sleeper didn't really notice much. We read the happiest baby on the block's sleep book and Healthy sleep habits, happy baby and happy twins.
If you want them separate, I'd put the good sleeper in the pack and play. I would not sleep train one on a different place than where you want him to ultimately sleep. That kinda goes against the logic of why you sleep train in the first place. You'd be "training" him to sleep in one set of circumstances only to change it.
