7. Cut back on caffeine
Coffee, tea, cola and energy drinks are mild stimulants. There are concerns that too much caffeine may increase your risk of miscarriage. It's also thought possible that too much caffeine may contribute to your risk of having a low-birth-weight baby.
Current guidelines state that up to 200mg of caffeine a day won't hurt your baby. That's the equivalent of two mugs of instant coffee.
As with alcohol, you may prefer to cut out caffeine altogether, particularly in the first trimester. Decaffeinated tea and coffee, fruit teas and fruit juices are all safe alternatives.
