How can I ease the discomfort?
While not as painful as true labour, Braxton Hicks can still be unpleasant. Common triggers include being active, someone touching your bump, having a full bladder, being dehydrated or following sex.
So don't get overly fruity when you need a wee and are gasping for a cuppa. Seriously though, changing what you're doing can often help, so if you're lying down get up, or, conversely, if you're walking around stop and put your feet up.
Practising your breathing exercises, a warm (not too hot) bath, or, as dehydration is a trigger, drinking a few glasses of water can also help.
