My DD is 5 months old and is currently sleeping in a sidecar arrangement in a grobag. I'm EBF with no plans to stop. She was full term, healthy and I don't drink or smoke. I'm well researched on the dangers as well as the benefits of co-sleeping and will follow the rules to a T. I instinctively feel that the best place for her is next to me.
She's getting too big for her Next to Me crib and I'm either going to convert a cot and attach it to my side of the bed or just bring her onto my side of the bed which will be flush to the wall.
Whilst I know all of rules available...I'm still a little unsure of practicalities such as bedding, clothing etc...
Can I keep her in a grobag or will she be too hot with my body heat?
How am I supposed to stay warm if I'm only half under covers?
Blankets or duvet pushed right down?
Do you sleep with a nightlight on?
I'm looking to fill in the gaps of how to do this sensibly and safely. I'd love to hear your positive experiences and tips please? 
Also - and this is the only but I'm unsure of - is it really unsafe for her if my husband who is on the other side to me has had a few drinks? Not taking about steaming drunk, but a couple of bottles of beer with dinner for instance. He doesn't smoke.
