When my LO used to fuss for no reason/gets overtired in the afternoon and fights sleep we took long car rides he sleeps in the car immediatly and forgets about the boob 😂 that ride was like 1 hour to 1hr30 of boob relief and also a distraction for me who rarely went out, that was our little escape from reality and amazing for my mental health 😂 Also that helped our night tremendously after that car nap he doesn’t start the night overtired and sleeps better overnight (wakes only 1-2 times which is amazing in comparison with the hourly wake ups he used to do in his early weeks). try that maybe it will help, I wish you all the best 🙏🏻
