My DD (9.5 months) has just learnt to go from lying to sitting. So thats what she does....all the time. She used to be ok with her sleeps in the day (nighttime dummy issues but thats a separate story).Now - I put her down & she sits up & bangs her head on the end of the cot. I am going in to lay her down sometimes 10 times before she is so tired she goes off. I have tried leaving her, and she then does fall asleep sort of half sitting up - I can then go in and lay her down but it seems a bit mean!! Is this just a phase? Or are there any tips!! My DH has suggested nailing her grobag to the cot (I think he is joking!!) Thanks
