We colsept 100% with DS until he was one, then he would start the night on the crib matress on the floor next to our bed (he refused to sleep in the crib) until he woke up and then he would climb into bed with us. We weaned from BF when he was 16 mo. cause I was PG. DD now co-sleeps and DS moved to a toddler bed at 20 mo. He still frequently ends up in our bed before the end of the night, but does stay in his own bed some nights. As for having both of them in bed with us, (DS is 2, DD is 6 mo.) we put at least one adult between them (usually me squished in the middle).
