normal ???

Help! my 3 weeks old baby has been latching on and off since 10:30pm. it’s 3:30am now. What’s wrong?😣 just when i thought it’s done, a few minutes later he cries asking for more and searching for the nipple when i cradle him and when i finally managed to cradle him to sleep, i put him down, his eyes are suddenly so wide open and cries to latch again. and this repeats im worried that he wont have enough sleep that he needs as a newborn
