He slept very nicely until 4 months old thank you. In bed awake. Go to sleep. Sleep 4 hours. Feed. Back to bed 3 hours and so on. Lovely. He is 10 months now.
Every single thing, waving, clapping, crawling has led to complete mayhem. Add in every cold, sick bug and tooth since 4 months and we have not had a single week without some kind of upset. I have not slept more than 2 hours at a stretch since he was 4 months. Usually it is less than 1 hour. Actually I can't remember when the last 2 hour stretch was it has been that long.
He started pulling himself up today which explains the mental lack of sleep the past few night.
Ds1 didn't see the need for this 
Neither did dd I don't think. She just woke every hour for a feed consistantly until she was about 2. Then she woke for a back rub every hour .
I actually now look back at dd's sleep with fondness because at least she went back to bed between wakings and could always be sent back to sleep by breast. Ds2 doesn't really do settling between his wake ups even with a nipple in his mouth. Then you get the bits where he screams at me for putting a nipple in his mouth, which oddly is my best chance for sleep because then dh walks him up and down the stairs for half an hour to resettle him
