Hello, I've put my little girl to sleep last night and she was up every 30 min..from 8pm till morning..she would wake up after 30min,I would give her dummy,would fall asleep,spit out the dummy,30 min later up again,crying,gave dummy,spits it out in her sleep,30min later up again..went like this all night..fully up from 5.50...her usual time..I'm exhausted..she never used to be a sleeper,after she was born she was up a lot,got better ,would wake up 3-4 times at night to be bf, then she hit 12w and since then she would not sleep properly..would wake up every 2h..then it got a bit better again at 5m..she dropped 3am feed,and would only wake up around 1am and then 4am,up from6, for the past week it got worse again and I've been up for most of the nights..goes to sleep at 8,would be up at 10,11,1,3,4,5,6...and last night it got to 30min intervals..she doesn't sleep much during the day (nap at 8.30, then 11.30,and around 4pm) and only sleeps for 30min,she doesn't know hot to get from the light into deep sleep,she is very tired but will fight it. She also started to turn on her belly when 18w and since then she keeps crawling in her bed at night,I have to pin her down when putting to sleep,hold her hands, but she will keep kicking and lifting her legs until she falls asleep..changed her meals this week,replaced a bottle 150ml with a solid lunch,which she likes,and finishes all, she like to eat, and still has 4bottles a day..could it be coz of that? I just don't know how to sleep train her..we tried c crying method..didnt work,she can scream for hours and would take me then hours to calm her down..but also don't want her to get used to dummy and keep putting it in her mouth all night...she is also teething badly for the last few days,can see canine tooth,tip of the tooth at the bottom and tip of her back molar..I know they usually should have front teeth first but those teeth are there and she is biting very agressively everything and is cranky and crying a lot..so could it be the gums? Really don't know what's going on and dreading tonight..so tired can't even think properly..any ideas? I'm used to not to sleep now and usually manage on 2-3hours a day but this is just too much...
