when we had our second baby, me and hubby were sleeping on the main bed with the first child, while i got a baby cot to place the baby next to me. it came with a pull down side, which turned it into a co-sleeping cot for sleep time. it was easy as baby had her own space to sleep without having to get on the bed, and everyone had ample space to sleep :)
My baby sleeps in a cot and I actually prefer it that way. I am always paranoid that either hubby or me will roll over her. Another alternative is to have a cot attched to your bed - a co sleeper. The one by Chicco seems to have good reviews.
our toddler and second baby sleep in between..😀our arrangement (me, second baby, toddler,my husband)..coz they want to cuddle w/ us
