I’d be too scared of causing my child to feel alienated to do it even if she agreed or even suggested. She doesn’t know how she will feel once the baby arrives and has the room, as a mother it’s your job to preempt those feelings and deal with them. If you need to move a child into the garden to make way for the new one I’d suggest you don’t have enough space to have another child but that’s just me.They have one of their gifted snuzpods in their bedroom though. The baby won’t be moving into its own room until next year - they could’ve let Betsy have one last winter in a warm house Unless it’s so Betsy can make as much noise as she wants of an evening with her mates but she’ll still have school the next day. Who knows - I’d hate it but it’s up to them I suppose
