Can anyone tell me how long this lasts?? Beginning to lose the will with naps, PM nap DD ( 9 month 18/6) fights and fights and fights. Resorted to Pram and car just to get her to sleep. Now some days the AM one is short! Night sleep not affected, she's ST and I watch wake windows and cap the first nap at an hour. She can and has taken all naps and night sleep in her cot. Tell me it's a phase and will pass. It's killing me as there's only so early can put her down to bed for the night.
