Thank you all for your responses. Like some fellow zombie mums
have said, my DD has always been like this, I always felt she was overtired but other than give her every opportunity to sleep I don't know what more can be done, believe me, if I could have forced her to sleep, I would...
When she dropped to one nap I kept her up until 1pm as I was told by a friend that 1pm - 3pm is a good nap time. I managed this for a week, she then literally fell asleep in her lunch 3 days in a row and I couldn't keep her up.
We have let her just do what she wants in terms of sleep also, she will fall asleep at 10am, wake an hour later and then scream if I try to put her down for an afternoon nap, even though is clearly tired. We are talking the kind of screaming that turns to coughing and then retching, we then are past tired and bombing about until bedtime.
In terms of nap time she averages an hour, sometimes 40mins, sometimes 2 hours (though this is VERY rare. Think can count these naps on one hand), more often than not is around an hour, I have tried leaving her to resettle, going in to comfort her, even tried wake to sleep at nap time. Nothing I do seems to affect the time.
I have tried wake to sleep, my DH thought I had lost it, getting up earlier to try to get her to sleep longer, tried this for a week, no affect. We have tried keeping her up later, later dinner, taking her out in the afternoon, torturing her by trying to keep her awake in buggy on way to/from park, no difference, we only managed to do later bed 3 nights in a row before I really felt like all we were doing was just upsetting her as is wasn't affecting the sleep at all.
We've tried pitch black room, night lights sleeping bags, blankets, heating on 30 mins before wake to make cosy, heating off incase too hot, bedtime 'aids' with soft light or sound.
Nothing has made a difference, if she was early riser and not so tired looking I would accept she is an early riser but to me I just feel she is over tired and I always think she looks tired in the morning... She also won't eat breakfast when she gets up until about 8am so I know she isn't hungry, have tried giving her a drink incase thirsty, isn't fussy.
I haven't tried putting her to bed earlier, everyone I have spoken to in RL seems to think I put her to bed too early, I will definitely try this, I am willing to try everything. Thank you all for your suggestions and experience.
It is so frustrating, yes I am tired, but I also hate seeing her look tired, my DN sleeps 12 hours solid and naps for 2 hours every afternoon, my DB has done no sleep training, he just fell into it naturally and he is 12 months older than our DD so I think there is something in some are just naturally sleepers and others aren't.
Any other suggestions I am happy to try and really appreciate all of your experience, I will report back if earlier bed has any success. If you told me to dance outside 20 mins before bed time I probably would! Thanks so much for your responses!! It does help to know am not alone too
