So sorry OP.I lost a baby at 16 weeks late last year, very similar to you - routine appt with m/w, no heartbeat, referred for scan which confirmed exactly what I didn't want to hear 10 days after that I was still mostly in bed, I think it still felt surreal at that point - I have 2 DC like you and they did help make things feel a little more 'normal', there was a kind of routine for their sakes.
