I've taken the whole 'don't lift heavy things during pregnancy' with a pinch of salt, as I was reading a pregnancy book or two where comments were made along the lines of 'during my first pregnancy, I was barely allowed to lift a shopping bag, but by my third I could lug a sofa across the room without the hubby lifting an eyebrow'.
Now I would say that's a bit exaggerated, but that was sort of what I went by and I have therefore not been overly delicate with myself as I didn't want everyone to think I was milking this for all it was worth. I never lift anything that causes me to strain overly - so if I have to tense my tummy muscles a little, it's ok (think the weight of 4 2ltr coke bottles), but anything more I keep away from.
However I recently had a shopping bag snatched out of my hands with much scolding and now I am wondering if I have been being silly and risking my pregnancy. How heavy IS too heavy?
