Feel for you Duende, am still going through this and my DD is nearly a year!
Check the room is not too light, I know since I got a black out curtain DD has slept better.
Could be teething so therefore feeding more for comfort (and to help grow teeth) as teeth seem to push through more at night.
Could just be he is so excited at his new skills that he just can't contain himself and wants to try them out. DD used to try and crawl in her sleep!
Have now switched DD to one longer nap in the afternoon after her lunch so that she is more tired at bedtime, sometimes works .
This is what I have been doing with DD:
At first with DD I put her in her cot and rubbed her back/ear/head whilst she listens to her glow seahorse until she went to sleep. If she tried to get up and play I would tell her to lie down and if she didn't I would quietly leave the room. She would get upset and cry, which I let her do for a few minutes before returning and telling her to lie down again. She soon got the message. After a few days I moved to rubbing her back for a few minutes then moving to sit next to the cot where she could see me (again if she didn't lie down I would leave the room as before). Then I moved to sitting away from the cot, then sitting on a bed in the room, now I am trying to move towards the door in an effort to just be able to put her down and she self settle to sleep. Who knows maybe I will be successful.
I am also trying pat and shhh if she starts to wake in the night, also winding and now send DH into her in the earlier evening until I feed her when I come to bed. I am going to start offering water if she wakes in the night to see if she will eventually just not bother waking. Last night she fed every two hours, you are not alone!
It is terrible being sleep deprived, if you can try and catnap when he naps in the day, I say leave the cleaning at what ever else needs doing your sanity is more important!
