Great night! And yes to 6 BT!
PS agree to short cn if he takes them...ds wouldn't do well with them either until 1-0 got really messy. I would only do them when necessary so like you said nursery days and on ewu days...unfortunately before this is over he may get to a stage where cn will lead to BT shenanigans and that's when you have to go CT...
Hugs hon you're doing great xx
