Welcome, Marie! Sounds like you have a good plan in place; congrats on the weight you've lost to-date! Glad to hear you're off that plateau... those are the worst, aren't they?!
My starting weight was very close to yours. It's funny - I thought I'd never lose quickly enough, but now I feel like... wow, that year flew by!
Keep up the good work & I look forward to seeing more of your posts (when you get time with those three boys!
