Blimey, I think a gizmo that documented my sleep would be highly depressive reading. Sometimes when I'm sleeping badly I turn the bedside clock around so I can't see it. Psychologically if I don't know when, what time, how long and how often I woke up, then I seem to feel less tired.
I am lucky that DD sleeps and settles well, I know how hard it is for all of you surviving on little sleep. I empathise and you have my sympathy and understanding 
Am I the only terrible mother who gave her baby some chocolate at Easter?
DD is the first of my children not to take to a beaker. It's kind of thrown me because I wasn't expecting any hassle getting her drinking, not had a problem with the other three. After deciding that her recent hard poos are down to dehydration, I cannot get her to drink from any of the dozens of beakers/cups I have bought - so she's drinking from a bottle, for now.
I've always thought seeing a baby drinking non-milk from a bottle was, well, a bit chavy and lazy parenting really. I am now evidently eating my words. Working hard on getting DD drinking from a beaker. But getting a good amount of fluids into her is more important for her health at this moment, so I'm accepting it.
My DC3 went straight to a straw beaker, I see these in the shop for 12m+. These were the beakers his older siblings were using at the time so he used to find his brother or sisters beakers and soon learnt how to use them. Don't have any now, but might try this with DD and just leave a few dotted around the floor to find and investigate.
