Wibu to leave ds, 8 days old, to cry?

[ACardiganForCat]

He wants to sleep on me or on boob all night. Parental advice is to shut the door and leave him to cry, he will stop eventually. Is this unreasonable?

I would say yes you are BU.
BUT
I asked the same question 12 weeks ago ........ my ds still sleeps on my chest
