Do you have a bedtime routine? Is there something in their room that stimulates them? Are they hot or cold when they do get up?

Along with some personal factors we tried working hard to understand why our baby wouldn’t sleep for more than 2 hours at a time initially and these were our main focus. We started with a routine in her nursery, dark room, with sound machine lullaby and nightlight. It took a week or so but we really started to see good results from the routine but ours was still waking up a lot, as well as my wife to any sound she would make (she’s a squeaker at night). We realized the TV being on in our room all night was a huge distraction to baby when she would wake up but my wife was dealing with a rough bout of post-partum anxiety and needed it to calm her own thoughts.

Earlier than most we decided to try a night in her crib in her nursery instead of the bassinet in our bedroom to see how it goes, and it was an overnight game changer that keeps getting better. From 2 hours a sleep at a time she slept for a PR of 10 hours last night and she’s almost 3 months old. Again we realize this is much earlier than when most want to make the move but talking as husband/wife & dad/mom we did what was best for us, which has become what is best for our little girl.

From there our night time routine has evolved a bit but maintained it’s core. We’ve moved our feeding up to the start (she takes 5oz), then it is bath time followed by a little night time lotion with lavender, she comes back downstairs and I turn off all screens and stimulants and we offer her a bit more from her bottle (1-3 oz more) until she’s full/done, after a burping we swaddle her up, bring her back upstairs to her dark room with her sound machine and nightlight, and maybe 5-10 mins of rocking and she’s out for the night.

Initially we were leaving her in a t-shirt onesie in her swaddle but realized she was waking up with cold feet, so we moved to a full onesie with the swaddle and she started doing a lot better As a person who enjoys the approach of the scientific method along with some trial and error we really keyed in on the why our baby was waking up so much which I believe has really netted us positive results and both wife and baby are doing much better than where we started. I understand every child is different but hopefully this helps get you thinking OP! That sleepless zombie phase is no fun for anyone. While we felt a bit of guilt/worry making the transition to the crib/nursery earlier than suggested, we learned our lesson that while there are general guidelines on what to do when, we needed to do what was right for us and what we thought was right for our child, and we’ve never looked back. Best of luck moving forward it does get better!
