hi, i have a 5 month old loveable ds during the day. by night he turns in to a monster. he started sleeping through the night at 3months and did so for 3 weeks since then hes been waking at least once and rising early (at 5am) surely he should be sleeping all the way through. hes formula fed on hungry baby milk. the health visitor has said he should go in his own room now and not to feed him at night. but that seems a little harsh. am i just being weak? as im back at work am starting to really feel shatterd now.
