Mam: Pregnant 33 weeks (Baby 31 weeks)
You and your baby are adding on weight every week from now on!
Of the half a kilo a week you're putting on, about half of that is your baby! 
With the hormonal changes, midnight toilet trips, leg cramps, heartburn and your basketball-sized belly, you will be finding it very difficult to sleep. Third-trimester insomnia strikes about three in four pregnant women (who may also be coping with anxiety about your upcoming birth). From this stage on though, your body needs to rest for the big event several weeks still ahead of you. Get as much rest as possible and try to relax before bedtime so that you get a good sleep. Try a warm bath and perhaps a warm cup of milk before turning in, avoid exercising, eating or drinking too close to bedtime and solicit your partner for a massage (you deserve it!). If sleep still eludes you, read a book or listen to soothing music until drowsiness sets in.
