4 Month Baby Update

Our little bear is 4 months old today! And he is seriously growing like a weed.

FullSizeRender (18)


We haven’t had our 4 month well check yet, but we did have a brief check-in at the doc’s last week, and at 16 weeks and he was 16 lbs 8 oz! At birth he was 8 lbs 10 oz. We’re getting close to doubling. At his two month well check, he was in the 85th percentile for both weight and length, and everyone is always amazed at how big he is for his age.

He’s mostly in six-month size clothing now, but can still fit in a few large three-month size clothes (and, above, he’s in a 6/9 month size onesie!)


On Thanksgiving (just shy of 3 months), he rolled from belly to back all by himself for the first time! Though he’s still not very good at doing this and hasn’t repeated it many times. What he IS a pro at, though, is rolling from back to belly (which is supposedly more difficult?)! One day I set him down on his back for a moment, walked away briefly to grab a water bottle, and came back and he was on his belly. I was shocked! He then proceeded to repeat his new trick about 20 times that day and hasn’t stopped since! However, he keeps getting stuck on his belly and has a really hard time rolling over to his back, so we have to help him out regularly. It’s really the saddest/funniest thing.

He also found his feet at about 3.5 months and loves grabbing them and rolling back and forth. This followed a month-long phase of obsession with his hands – staring at them SO intensely, entwining them, chewing on them. He’s still a huge fan of his hands, really.

We do think he may be going through some early teething pain. We actually took him to the pediatrician’s to rule out any illness a few days ago because he hadn’t been acting like himself – whimpering, rosy cheeks, poor sleep. Doc said he was all good though, and it was likely teething. A few days later he seems to be back to his old smiley self, but still no teeth, so who knows.

We also celebrated his first Christmas last month.



He absolutely LOVES seeing his reflection in the mirror. Apparently he won’t become aware that his reflection is, well, him, until well into two years of age, but he is a big ol’ ham when he sees “that cute baby in the mirror!” He also loves his new snail toy which has a mirror on it that he received from Grandma and Grandpa for Christmas.

When he is in a good mood, he also loves vocalizing, and went through a stage where he cooed “whooo, whooo, whooo” like an owl for a few weeks. As of late, he loves squealing in a high pitched tone: “ah, AH, AHHHH!!!!!” with a giant gummy grin and it’s literally the cutest thing.

Generally he’s a pretty happy smiley little guy most of the time.



Loud noises, being surrounded by lots of people, strangers, feeding from bottles, sleeping in.


Jack typically has five naps per day that last 30-40 minutes each. After he awakens, he hangs out for 90-120 minutes, then gets sleepy and needs to go back down for another nap. We absolutely cannot get him to nap longer than that. He also must be rocked completely to sleep before being laid down or he will fuss and cry and not go to sleep. Needless to say, rocking a 16+ pound baby to sleep multiple times per day is exhausting! It is seriously an intense workout. By the end, my heart is racing and I’m sweating (and back is aching.) I would love to be able to set him down drowsy but awake for naps but so far we’ve had zero luck in this arena.

Once he learned to roll at 3.5 months, we had to stop swaddling with the SwaddleMe blankets that we (and he) loved so much, for safety. Instead we’ve transitioned to size small Halo SleepSacks. His (and our) sleep hasn’t been the same ever since.

He has pretty consistently been going to bed around 6:30 PM since he was born. In the morning, he used to wake up around 6:00-6:30 AM, but over the past month, that time has been creeping up earlier and earlier… now if he sleeps until 5:00 or 5:30 AM it seems like a miracle. It’s not uncommon for him to wake up at 4:00 AM these days and just refuses to go back to sleep. I’m not sure if this is due to the lack of swaddle, the “4 Month Sleep Regression,” teething pain, or something else.

Prior to unswaddling, he typically would wake up 2-3 times per night, with a rare night where he’d awaken 4 times, and twice he only woke up once the whole night (As my co-worker who also just had a baby joked, I felt like I was on drugs the next day after getting so much sleep!) Most often it was just twice per night which was totally manageable. He started out with a nice long stretch – typically 5 hours, sometimes longer, and then would have another 3-4 hour stretch, which allowed me to get some sleep. Since he is breastfed, I am the one who gets up to feed him at every awakening since birth.

However, since we’ve stopped swaddling, he has been awakening more frequently and also stopped having those glorious long stretches of sleep. Now I’m commonly up 3, 4, or even 5 times per night tending to him. I’m desperately hoping that his sleep improves soon!


He’s still 100% breastfed and has quite the appetite. He feeds about 10-12 times per day at least. We have been struggling to introduce bottles of pumped milk to him in preparation for starting daycare once per week next week. I am going back to work part-time starting the first week of January, after being off for nearly five months.


While I miss seeing him as an itty bitty infant, he is absolutely becoming much easier and more fun as he gets older! I really think he was a high-needs infant with some colicky tendencies for the first 10 weeks or so, which seem to have since disappeared for the most part. Now he is just pretty happy and chill all day long unless he gets hungry or sleepy. This makes me much happier! Those first 10 weeks were honestly so hard.

I really think he could start crawling anytime. We really need to start babyproofing our house ASAP.


Looking forward to seeing what 2016 brings!
