I had one call with a sleep helper (not paid, just a retired Health visitor as we were all struggling a lot from the lack of sleep and no support at all - covid times) anyway, I cried after the call knowing I couldn't do it - I was told to remove all his sleep aids, no dummy, no blanket, nothing he was used to and if he wakes tell him NO, GO TO SLEEP, and then leave him in there for 12 hours with the door shut. He's 9 months and I went against her advice, I knew my baby was still waking as he was hungry and there was no way I'd leave him. Anyway, with eating more solids he started to sleep 11-12hrs (for now anyway!) sometimes he wakes and I go and feed and cuddle him, my heart would break listening to him cry alone. So, I know exactly what she did to get those two twins sleeping so early on, and I know it's so hard (my mental health takes a drop on continued lack of sleep!) so I don't judge those who have to do it like single parents. But her? With on-hand daily support, no job to do, a husband who can easily help out, she is one cold-hearted woman.
