Hi-just wondered if anyone else had any experience of this: - my son is 26 months old; a brilliant sleeper (rarely wakes and sleeps for about 11 hours), but over the last few weeks, he has been waking 2-3 times a night, screaming; really distressed - and when I go into his room and ask; 'Are you thirsty/hurting/do you want a cuddle?'. he says 'No' and settles quite quickly. Bit upset to think that he may be having nightmares and at such a young age and so frequently? Any advice/ similiar expereinces, please?
