Kelly said everything I wanted to say.

BUT I would like to add.
My sister had her FIRST baby when I had my fourth.
I didn't live close to her at that time and from what I know she didn't have a support network surrounding her like she needed.
She got sucked into what is the same as that woman preaches [the complete 100% opposite to my own way of Parenting a baby].
NOW after having baby #5 she says she can never forgive herself for puting her firstborn through what she was told was the right thing to do.
She calls it 'torture' [her own words]. And does everything she can now to discourage other new Mums from doing the same thing.

Good luck OP on your Parenting journey
