Yes I think I read somewhere that they're not entirely sure what causes morning sickness so they're not worried if you don't have it.
Not sure yorkshirepud! I didn't need to buy a maternity coat for my last pregnancy. Maybe I should dig that old coat out as my current one is too tight around the shoulders. A stretchy one sounds a good idea but not sure if they make ones to stretch over the shoulders lol 
Have bought some Gaviscon tablets in the hope they make me feel less like I need to eat all the time to keep the acid/queasyness at bay. Don't feel like eating my nighttime cereal so maybe they're working. I've already been dreaming about buying some Crunch Nut cornflakes though to keep "morning sickness at bay" aka let's pig out whilst have a suitable excuse so maybe they won't work for
long!
