Hello everyone I have such a question My son has been tossing and turning all night lately, he cries as soon as he wakes up, I give him breast immediately But it's literally just five minutes and then it starts again all night ? Could he not be getting enough to eat or what do I even know anymore? We are 8 months old, we introduced solids Maybe he isn't eating enough throughout the day ? Has this happened to you?
