SG I am totally new at this,and so reluctant to jump in with advice but I just read the last few posts of your thread and can't not reply.
You mentioned you are finding it hard to come up with 180s but then next few posts about who gets up in the night...there's your 180! Be first up to your son. Don't argue that she should ask for help if she wants it, just do it. Trust me, she will appreciate it. Getting up to children in the night is mind numbingly exhausting, mundane, repetitive, boring, and just plain hard work. Every mother feels taken for granted and wants more help with the routine stuff of life. Perfect recipe for resentment if she feels you are not pulling your weight...even if YOU think you are.

Thanks for posting. I think this is great advice. Even if W is up with S I can ask if she needs help. I can offer rather than assuming she has everything under control.
