1st trimester: Week 7

Exercise

Work out with light weights to tone your hamstrings, buttocks, lower back, and shoulders. It'll strengthen you for the demands of childbirth, not to mention give you the muscles you'll need postpartum to push a stroller, wield a diaper bag and a car seat, and carry a baby (hopefully not all at the same time). 

Relationships

Ask your partner to keep a running list of both your questions for your next checkup. You may be so overwhelmed with new information that you forget to ask any questions at all.

Siblings

Spend lots of one-on-one time with your older child in the upcoming months. Let him pick the activities (watch The Lion King for the umpteenth time? Sure!), and tell him now how much you value having fun together. After the baby is born, it will take a lot more effort to get this one-on-one time with your other family members. 

Twins

Women carrying a single baby are advised to add 300 calories to their daily diet. On top of that, women carrying multiples need another 150 to 300 calories for each additional baby, says Ellie Krieger, R.D., nutritionist and new mom. That translates up to 600 extra calories a day for twins and 900 for triplets.
