Basically the title.
DD is 11m and has always been a terrible sleeper. Up until around 8m we used to feed to sleep and contact nap/cosleep for every single nap. Daytime sleep became completely hit and miss and not being able to get some stuff done while she was asleep became unsustainable. I began taking her out for a walk in the pram and up until the last couple of weeks it was working amazingly. Now suddenly she is so interested in everything around her that a walk is almost more stimulating than relaxing, and walks end up with her screaming.
Now I'm completely stuck. I'm mindful of the activities we do leading up to sleep to make them calmer, I draw the curtains, we'll read a couple of stories, I'll put white noise on, I'll give her a feed and even lie down with her... nope, she is still raring to go even though she will be rubbing her eyes and yawning, she just wants to crawl and play.
Timing make no difference (rigid or flexible), she never gets into a quiet, relaxed, sleepy sort of state even though I try to facilitate the right environment and time for her to wind down but nothing seems to make any difference.
I'm at such a loss now and feel like I have zero idea what I'm doing in the sleep department. I just want the challenge that is sleep to get easier rather than worse.
