Pregnancy: Week 21

Hi Everyone! Happy Monday!
I'm 22 weeks pregnant today! Here's how the past week has been:
- Nausea: Controlled for the most part with 1 Zofran/day (down from 2/day); trying 1/2 per day this week
- Backache: Much better since going to the chiropractor
- Insomnia: It's been a horrible week for this, capped off by being awake until 5 AM this morning, and then having to get up for an 8 AM conference call. Every night has been several hours at least of not being able to sleep. It's some combination of discomfort (mild nausea, mild backache, joints aching) and reading baby books late at night and starting to freak out, eg: "Will I ever sleep again once the babies are born?" "How in the world am I going to breastfeed two babies with my breasts as sensitive as they are?" "What if one or both of the babies has colic?" Etc. In short, all things we'll figure out as we go along. All things there's no sense in worrying about now
- Mood: Generally happy (tired, but happy)
- Exercise: Trying to walk every day, but it's really been more like every other day. My prenatal yoga class ended a couple weeks ago...going to see if there's a gentle general class I can join. Thought about getting a yoga DVD, but doing yoga in my living room by myself just doesn't sound like much fun
- Weight gain: Still right on track. I feel enormous, and there's still such a long way to go...
- Baby prep: We've been doing a lot now that we know the sexes. Getting close to having names (at this point, just trying to figure out our girl's middle name). Bought flannel for the receiving blankets my mom and I are going to make. Looked at material for quilts and curtains for the nursery. Looked at prints (wall art) for the nursery, and while we still need to decide, we found some we like. Working on making a decision re: cloth vs disposable diapers (anyone have any thoughts on the matter?). Got some baby shower details figured out. And my mom and mother-in-law have been buying the cutest clothes imaginable...all second-hand...it's amazing what you can get. Etc. All this is so much fun, I can't even tell you...
Hope everyone has a lovely week!
XOXO
