My son normally feeds every like 3 hours at night but the last couple nights he's been trying to feed every 45 minutes. I say trying to feed because he'll latch on for like 15 seconds and then start screaming again. Hes 11 months old so I know technically he doesn't need to eat at night but he alway has he normally eats twice during and 3 times at night. Could it be my milk supply dropping or is he just going through a phase?
