Halo Sleep Sacks - we have two of these, and they make bedtime peace of mind that much easier to attain. I know that Charlie is unable to pull any blankets over her head, and that the cozy fleece will keep her warm when Seattle nights are cold.
NUK pacifiers. We've tried MAM and Gerber, but NUK is the clear winner. She can keep it in her mouth, it doesn't gag her, and she won't leave home without it (or she "lectures" me the whole time we're out if we do.) Infantino Twist and Fold Gym in neutral. I LOVE this thing. It's brightly colored animals entertain Charlie for hours, allowing me to do laundry, knit, read, or do anything that requires two hands. It will be a sad day when she outgrows this charming little floor gym.
Munchkin Arm and Hammer Disposable Bags and Dispenser. A friend brought this to us when she came to meet Charlie the day after she was born. These puppies are lifesavers, disguising the disgusto-smell of dirty diapers with a pleasant baking soda based scent. Since most places (including the doctor's office) don't appreciate you leaving stinky diapers in their trash cans, these can make the task of taking them with you much more pleasant.
Sony Baby Call Monitor. As paranoid new parents who hadn't been told that babies breathing patterns can be terrifyingly inconsistent, we bought these monitors after a trip to the ER. Did you know babies can stop breathing for up to 10 seconds and it's normal? Neither did we...till the nice ER doctor told us. (By the way, when in doubt, definitely utilize a nurse consulting line, your pediatrician or the ER - peace of mind is so worth it.) Anyway, now we can hear all of her strange sleep sounds and over time have learned which one's warrant checking on, and which are just throat clearings.
Nail clippers with file. Oh poor Charlie's fingertips. So brutalized by nail clippers alone. Now I use clippers to trim a bit and the file to get them as short as I need...files can't cut jerky fingers like clippers can.
Trumpettetoo socks. These stay on! Hip hip hooray! Plus, so adorable.
Baby Jogger City Mini Stroller. Best stroller ever. One handed maneuverability, plus one handed fold, and-wait for it-17 pounds. Yeah, I know. Amazing.
So, that's it so far, I'm sure there will be many more favorite things to come. What are your favorite things?
