Welcome to the Quilting Board!
I don't really have anything to add about McTavishing, but do about babies and sleeping
When I had my first, and really with most things, I tend to use what seems to work best, common sense-wise. I was taught at the hospital to put my son on his tummy. Seemed to me, when he spit up, if he wasn't watched like a hawk, there was a danger of inhaling it. I listened to what they said at the hospital, on the back was bad, and it just seemed to me, he was more comfortable on his side. So that's what I did, bunched a blanket up, or something, and propped him on his side. Oh my goodness, what would the expects now say about that!
But, my Dad was notorius for rubbing whiskey on a baby's gums when they were teething too, and giving them a pickle, and all his kids got a glass of pop (in Ohio, soda in other places) before they went to bed.
Point? It's in my dna, a rule breaker!
You know that feeling when you've finished all your quilting projects and your studio is perfectly clean???? Me neither.
It's not how fast you sew, it's how well you sew fast! Wait, I think that's supposed to be MOW!
