5 months old, waking 3-4 times a night. Wife exclusively breastfeeds. I dropped the hammer on that little baby last night. He moved into his room, the 3 yo boy moved out of the girls room in with him. And so did I, for a few days anyway. This is my 5th child to sleep train. I can literally do it in my sleep. Wife is showing renewed energy, signs of life. We waited long enough. Yeah he cried for 30 minutes while I progressively backed off my verbal re-assurances, sleeping in the unused top bunk that will be his someday. Yeah the 3 year old slept right through all of it. He startled once to a new room confused, I laid with him back to sleep. They won't even really remember their old sleeping habits in 3 days. The first night is always the roughest but when you hold the line it's over before you know it and you have good sleepers. (as long as they are together)
