ooh cheezel i can totally feel your pain!! we've had similar times with DS - it's always up and down and at the moment we're having that same problem with not settling for at least an hour. this is only since we moved him from his cot to his bed. i think they somewhat enjoy the novelty for a period of time. it's exhausting and emotionally draining though isn't it.

i've had much advice along the way but i think the one thing that has worked relatively well is to have a pre-bedtime routine and to try to keep the actual bed time consistent (eg 7:30pm each night). for us, we keep the tv off and try to keep things low key in an attempt to wind him down. we do bath, quiet play, cuddle, BF, bed - but just do what works for you.

and remember that things do change and they will get better in time anyway, no matter what you do. our little ones do test us don't they
