In Spain they have a saying “Cada relación es un mundo” which translates to “Every relationship is it’s own world”.
I think the same applies for parents and their babies. There are no solutions that work for everybody. Every baby is different and changes constantly. I will write about how things worked out for us, which doesn’t mean that there aren’t any better ways of doing things. Feel free to use what’s interesting for you, and discard what is not!
