When did your baby start sleeping through the night? Please indicate if co-sleeping or baby sleeps in crib.

My baby started sleeping through the night at about 3.5 months old. She now sleeps from about 10pm till 6pm without a squeak. We removed one side of the cot so it functions as a co-sleeper but recently we started to co-sleep with her by placing her in between us. It's actually not very good for couple life, so we'll move her out when she turns 1yo.
