how did you introduce a blanket and pillow in crib? we live in Ohio and it's going to start to get cold soon. we want to give them a blanket when it starts to get cold and possibly pillow. they are 13 months and are still in the crib and not toddler bed yet. we think they will learn to crawl out soon I will have to transition to the toddler bed. what type of blanket did you use? when you introduced a blanket did it help them sleep through the night if they weren't?
