We had his 4-month checkup on Friday, and he's still in the 95th centile for weight (at 18 lbs., slightly less than I thought) and 97th centile for length (at 26"). Dr. Martin is really laid back and thinks Zephyr is doing great, told us to ignore the books that say the babies are supposed to sleep through the night at his age. Of course, I can't. I decide she's just trying to make us feel better and take matters into my own hands.
So, last night I decide we're gonna try our hand at sleep training. I'm drunk on power, having discovered the secret to getting Zeph down for solid naps (and seriously, getting two 3-hour breaks a day is delicious), I think we can totally do this. I formulate a plan: when he starts crying, give him five minutes, then gently soothe him back to sleep by patting his back but not picking him up or feeding him. That's what the No Cry Sleep Solution book (err, the summary of it that I read online) said to do. So we give it a go.
Scott and I settle into bed at around 11:00pm, and after a couple hours of blissful slumber, Zephyr starts fussing. I decide to firmly ride it out for five minutes, instead of just reactively bringing him to my breast like normal. His fussing escalates into full-blown crying. I pat his back, "it's okay, Zephyr, go back to sleep." No dice. I look at the clock. 12:50am. The crying isn't slowing down, and now Scott and I are both completely frazzled. Zephyr is starting to totally unravel. I try patting his back again, with no results. I look at the clock again. 1:11am. Sigh. This feels mean and neglectful and exactly like the cry-it-out method (which I'm pretty sure has never been attempted in a cosleeping situation), I'm at my wit's end and scoop up my baby to soothe him and fret for being such a disastrous mother, planting apologetic kisses all over his tiny, tear-damp head. He starts mouthing on my shoulder before I even get him to my breast, and then nurses frantically back to sleep. It takes me probably two hours to get back to sleep after the ordeal.
This afternoon, I read the Going Through the Night Without Being Fed section of Penelope Leach's Your Baby & Child and realize that I hadn't been doing anything wrong at all until I decided that we were going to try to fuck with Zephyr's sleep habits. The kid needs to eat a couple times at night, and this is completely normal! I feel renewed as a mother, have reinstilled faith in my pediatrician (whom I already trust and should've just listened to in the first place). One neat trick that Leach offers, though, is to wake the baby to nurse when I go to bed instead of waiting for him to wake up at the four-hour mark. I can reset his tummy-clock myself to get a full four hours of sleep for myself. Now that's sleep training I can get with.
In other news, today Zephyr had his first poop in FIVE DAYS. I know it's normal and common for babies to go several days between poops at this age (particularly breastfed babies), but holy shit, it totally freaked me and Scott out! And then when he finally did poop, it went all the way up his shoulder blades and required a full bath. But lemme tell ya, he's been a much more pleasant kid since. Tummy time was thus extended with comfort and ease, offering me a chance to shoot him in his new pants. It's motherfucking doughnut time.
