Sleep is one of those truly delicate subjects when it comes to babies. Disclaimer: Please know this is just our own story and one I wanted to share to a) give insight and b) document as much as I can. The absolutely safest sleep setup for babies are as followed by the APA is as followed: alone in their crib, placed on their back, and in their parents' room for the first year.
Ever since the day Harlen came home from the hospital, he has slept in a DockATot every single night (see: a tiny H in his first DAT.) As colicky as he was in the newborn stages, he consistently slept between 5 to 7 hours every night for the first stretch ever since he turned 1 month old. I realize now how completely lucky we were as first time parents that this was happening regularly.
We had removed the DAT around 4 months mainly because he outgrew it so quickly. (Hi, 99th percentile for height.) Between 4 months and 8 months, sleep regression, teething and a cold all happened and sleep his nightly sleep schedule was all over the place. We tried moving him to a crib during this as well, but good sleep was still hard for him. And us. Gone were the consistent 5 to 7 hour stretches we were so lucky to have.
One sleepless night, I told John "we really need to get the DAT back into our lives." Enter the DockATot Grand. He has so much room in this new DAT and still has room to grow with it. Would you believe he's been consistently sleeping 10-12 hours every night now? We start our bedtime routine at around 7pm and is usually asleep no later than 8:30pm. He still wakes up for 1 quick feeding around 1/2am, but goes back to sleep quickly and sleeps in until around 6-7am, and even 8am a few times since the new DAT Grand.
It's been such a learning experience (and still is) navigating through parenthood, so figuring out something that has worked for our family, especially sleep, is the best feeling. Fingers crossed his sleep stays consistent and only gets better as he gets older.
