About fathers must bond as early as possible.
My DH was away in merchant navy when DS2 was born and did not see him till he was two months old.All the bonding came later on, when DS was misbehaving as a teenager.
Baby slings
I had one for both of my sons.It was a Mothercare one and went across your body, I only used it when going out though as I found it got in the way in the house.My SIL told me she had what she called a ''cuddle seat'' for her youngest in the 60s.She used it for going on the bus with him.My grandmother's generation hardly used prams for the first few weeks, they carried their babies around n a shawl.
I remember my grandfather telling me how his mother, who had seven children, leaving the baby in a wooden cradle in the bedroom while she got on with housework etc. This cradle had rockers, and she had a rope attached to the bar between the rockers which was fed through a hole in the floor and the end hung from the downstairs ceiling.Whenever the baby was heard crying, she, or anyone handy, would tug on the rope to set the cradle rocking so the baby would hopefully go back to sleep until she was able to attend to him/her.That was my greatgrandmother's Attachment parenting.
