Sorry if this is in the wrong place. I have an almost 4mo old grandson who has trained his parents on his own schedule which is 45minutes sleep, awake & screaming the rest of the time unless held or being fed. (its not colic) These are the only details I have, other than parents at their wits end & mom seriously sleep deprived. I know there is something they can do to reverse this as in teaching him to sleep without getting picked up at his command..its a complicated issue but I bet some of you have been there and trained baby to be on more realistic sched!! These are fisrt time parents.
