My 12 week old DS is still waking to be fed every 2 hours at night, sometimes it's only 90 minutes and it's killing me. He has always been a short feeder and will do between 5-10 minutes and be done.
In the day time he can easily go 3 hours between feeds as he plays for 90 minutes and then will have a 2 hour nap at lunch time.
Why can't he go longer at night? Is he not taking enough at each feed to keep him going longer?
