We sleep trained DC1 using the ferber method when she was 6mo and it worked a charm. We started one night and then went straight into naps the next day and she was trained so quickly but it took about 2 weeks for it to become embedded. It was easy to do because it was lockdown so we spent all our time at home. Fast forward and now thinking to train DC2 but it's just not possible to have every nap in the house when I have DC1 to look after. Will the ferber method still work if its not done in a consistent block? I don't want to start training and it not work and then have to do it again. Any advice?
