I'm just glad there was no internet when mine were babies - I would have been an underachieving basket case if there was.
I hadn't heard of Gina Ford or attachment parenting or any such stuff when I had mine (only 2002, so not that long ago). All I had was advice from mum and health visitor.
I had a bottle fed baby on a 4 hour feeding routine by a few weeks old. Weaned at 3.5 months and sleeping through from 8 to 8 by about 6 weeks iirc - off all bottles by 6 months and no sleep regression or dramas since. (I am a person who likes to be in control and organised).
My way worked so well for me I did it again with my next baby, exactly the same with the same outcome.
My friend bf and had no routine, did what would now be called a 'baby led' wean and the baby was still night feeding until well over a year iirc, she was totally into 'following her baby's cues on everything. (I always thought she was a bit of a hippy and never understood her way of doing things).
Her way worked well for her so she did it with her next baby.
12 years later all of our children are doing just fine. They're sleeping and eating fine, with pretty typical behaviour and school achievement, they are all happy and well adjusted.
My point is this:
when your child is older, nobody can tell if you co-slept, cried it out, breastfed, bottle fed, baby led weaned or weaned traditionally, used a sling or a buggy etc etc etc, and more importantly nobody cares. How you feed or organise a baby's day makes no difference in the grand scheme of things.
Imo, the best way to do things is to cherry pick the bits that work for you and ignore the bits that don't - slavishly sticking to a "style" of parenting is a recipe for mental health disaster imo. One size does NOT fit all when it comes to parenting, but it's so easy to get caught up in it all and feel a failure.
