Hi all, so my fourth little one is 21 months old and has been sleeping well in her cot bed in our room since 6 months, we do zero co sleeping and she sleeps from 7pm to 7am. I was ready to move her in with her sisters (5yrs and 4yrs) pre Christmas as they have a huge room but then my friend unexpectedly lost her baby who was only a month younger than my DD 8 weeks ago and now I am so distraught I am nervous to move her. Will she still be OK to stay with us for another few months until my nerves settle?
