1st trimester: Week 8

Siblings

Make the most of your time with your firstborn by scheduling special one-on-one playdates with him. Buy a craft kit and build it together, attend a ball game and make an event of it, or explore a new neighborhood together. When the baby's born, you may not be able to give him as much attention as he craves, so load up on the fun now.

Strengthen Your Family Bonds:

• Preparing for Your Second Child
• Nursery Sharing 101
• Helping Siblings Bond
• Read "Baby on the Way" together

Twins

On average, mothers pregnant with twins gain between four and six pounds in the first trimester. For the rest of the pregnancy, they put on approximately one and a half pounds per week.
