So I guess I really have two questions...

1
During the daytime, if I want to cosleep when she is sleeping, can I put her down on my bed and sleep next to her? I have one of those sleep positioner things that I was hoping to use. Can I use that sleep positioner to put her to sleep on my bed and then leave her sleeping there? This is only while she is so young that she can't sit up or roll off the bed etc.

2
How do people move around the bedroom in the morning? DH will wake up before me and rumble through his dresser to find clothes, and then go into the wardrobe to get shoes etc. If you cosleep, doesn't this wake up the baby? What if you need to go into the bedroom while the baby is sleeping?

Sorry, silly novice questions!
