I am an old gimmer. Consequently I have seen decades of 'mothering fashion' come and go e.g. sleep babies on their backs, no, on their tummies, no, on their sides, no, on their backs (again).
Potty train, don't potty train, let it happen naturally, potty train (again)
Let baby sleep in your bed, no, don't to that you will suffocate the baby, no, of course you won't etc. etc.
Breast feed, no, bottle feed, no breast feed (again)
Be a SAHM, no, nurseries produce a more independent child, no, be with your child at home etc. etc.
All intended to induce guilt no matter what you do, written in blogs and books by people who probably don't know any better than you do.
FFS All we need to know is that you love your child, do your best for its health and happiness, understand your child, treat your child with kindness, compassion and consistency, allow your child space to grow and achieve.
The rest is crap.
