Decisions based on previous pregnancies?

This is my #2 and I remember with my first, I couldn't sleep on my tummy from 2nd trimester and on my back in the 3rd. Towards the end my hips were killing me. But side sleeping was the only option. So now I make sure I sleep on my tummy for as long as I can so that the strain on my sides aint a whole 9 months.

Any moms of more than one also making funny decisions due to anticipation of what will happen based on how previous pregnancies treated you?
