Pregnancy Week by Week

Get a window on what’s happening in your pregnancy, week by week. From week four to week 42, your baby is experiencing a miraculous transformation from a clump of cells to a fully formed (and totally cute) newborn. Just imagine, as early as five weeks, your baby is already starting to form major organs (heart, stomach, liver, and kidneys) and systems (digestive, circulatory, nervous). By eight weeks, your raspberry-sized womb-mate is moving her arms and legs. At the beginning of your second trimester (week 14), your wee one is sucking his thumb. By week 28, the first week of the third trimester, baby (now as big as an eggplant) is prepping for breathing, developing his eyesight and packing on pounds in anticipation of life outside the womb. Each week is a new miracle. Less miraculous is how a mom-to-be may feel. Pregnancy Week-by-Week charts your baby’s development but also lets mom know what she might be feeling during each week of her pregnancy. Pregnancy week by Week includes everything mom needs to know to feel a sense of control over her pregnancy. Each week offers a complete guide to what you might feel, your must-do’s, your nice-to do’s, and answers and advice on everything pregnancy-related. Plus each week’s guide offers tips on maintaining a healthy and comfortable pregnancy from strategies on coping with pregnancy symptoms (morning sickness anyone?) to ideas for healthy eating, and pointers on talking to your OB. Let us guide you along your pregnancy, week by week.

Q&A: Thank-you note timing?

How long can I reasonably wait to send thank-you notes for gifts?

Re: How long can I reasonably wait to send thank-you notes for gifts?

The Bump Expert

You'll probably be very busy (and exhausted) in the weeks before and after baby arrives, and your family and friends are sure to understand. Still, it’s best to send out those thank-you notes asap. Try to send a thank-you for shower presents and other pre-baby gifts before the big day, if possible. (We know it’s tough, but it’ll be easier now than when you’re changing diapers and waking up at all hours.)

For the gifts that you receive after delivery (and the leftovers from beforehand), shoot for getting notes in the mail by the time baby is two months old. And, if you don’t make the deadline, don’t convince yourself that you’ve waited too long. The rule here is the same as with wedding gifts -- it's never too late to show gratitude.

Q&A: Thank-you note timing?

I plan to do the same thing I did for wedding gifts. I addressed and stamped all my envelopes and stuck a post it inside the card with a reminder for me of what I was thanking them for. I put them in a tote bag and carried them with me places that I knew I'd be sitting, like the Dr office waiting room. Each time I had a few minutes I wrote a note and sealed it up. I was surprised how quickly I got them done. I was hoping to get my thank yous sent before the baby came, but I know there is a surprise shower planned for me that hasn't happened yet and I have only 4 weeks to go, so if I don't get them all sent it will just have to be okay! A friend of mine had each guest at her shower address an envelope to themselves so that when she was writing her thank yous it was already done for her. Not a bad idea either.
