My 13 month old son has started waking up as soon as I put him down and crying but I don’t understand why. Normally I’ll BF him till he’s asleep then he’s out for a few hours but as soon as I put him in his cot he wakes up and I feed him again till he’s back to sleep then put him down and he’s awake again. I’m absolutely exhausted as he’s doing it at night and during the day I just don’t know what to do
