My LO will be 8 weeks old on monday and was extremely fussy at nights the past couple weeks and would sleep only in our arms and wake up the min we put her in the crib. So for the past couple days we decided to keep her up sonce 6pm. We would sing to her, play, do tummy time and by 9 shes getting so tired that shes sleeping for 6-7 hours straight in her crib, waking up for a feed sleeping again. Im so happy. I know it sounds brutual to keep her up from 6-9 in the evening but shes sleeping better at night. Maybe some of u monmies struggling with little night owls can try it
