Mums could be noticing little bumping movements across their belly every now and then. This might mean that baby has the hiccups! Foetal hiccups are much the same as the hiccups we get and are caused by reflex spasms of the diaphragm. In unborn babies however, this is due to the drawing in and out of amniotic fluid, rather than air.
Leg and foot cramps can cause sleepless nights at a time when you need to be stocking up on sleep. Make sure you're getting lots of gentle exercise during the day (short walks and swims will do the trick) and avoid standing still or in the same position for more than a few minutes. Putting a couple of pillows under your feet at night to raise your legs up might help as well. When a cramp comes on, flex your toes upwards and put pressure on the area with your (or your partner's) hands.
You can help ward off cramps by ensuring that you are getting enough potassium and calcium in your diet. Boost potassium levels by eating fruits like bananas, grapefruit and oranges. Sesame seeds, yoghurt, salmon, cottage cheese, almonds, sardines and soyabeans are also good sources of potassium.
