DS has previously gone for all naps and bedtimes with little fuss, no crying and will just lie there until he drifts off. The last week or so, however, he is fighting all sleep. The only way we can get him to nap at the moment is with us cuddling him otherwise he will scream until he's almost sick in his cot. Bedtimes were OK but have also gone to pot last few nights with him crying himself to sleep and getting really upset. Once he's asleep he's down for the night but it's killing me hearing him get so upset before going to sleep every time. He's not teething as far as I can tell as he's cut all 4 canines fairly recently and no signs of back molars yet. Anyone got any advice please?
