Does anyone else get this? My ribs really ache at the sides and back, especially when I'm sitting down for long periods of time, e.g driving. One of my friends suggested it could be LO's feet but I don't think she can be that big yet (22+4) so I'm guessing it might be stretching. So much bloomin stretching going on all over the place, it would be easier if we were made out of rubber!!
