Help please anyone. DS previously not so bad sleeper but for last 2-3 weeks has been getting progressively worse. Now doing only 45 mins naps during day and night. Goes to be at 7.30ish and up for 8.15 then he calms down very quickly and sleeps till 45 mins later - this carries on throughout the night and I have resorted to co sleeping as is easier to shush him to sleep or pick him up. Needs a dummy to self soothe and is biting more,dribbling and hands constantly in mouth so we think is teething but I hear that teething can go on for months before teeth come through and can't go for months with this sleep pattern! Anyone any ideas or anything similar? Please help - am knackered
