My 5 month old has always been a tricky sleeper but in the last couple of weeks has been waking earlier and earlier and now wakes anytime between 4.30 and 5am 
She only dropped her night feed about a month ago and would self soothe with the dummy and although she woke for that she would go back off til nearer to 7.
I can cope with 6am starts but I am exhausted with the constant night wakings and then the 5am call time 
She goes to bed around 7pm every night and it’s worth saying will sleep quite soundly until she wakes at 4, occasionally she is restless and needs the dummy being put back in.
She’s really not a good napper either, only going down for 30 minutes at a time in the day. I feel exhausted and feel like I’m not doing enough for her because other babies get so much more sleep. No matter what I try whether it’s pram, car, cot she will not stay asleep more than 30/40 mins max.
Because of her bad sleeping habits I feel she is growing more and more cranky as the days go on.
At home our room has a blackout blind, I play deep white noise in the background, she has a comforter and dummy and can normally for the most part get herself to sleep.
Does anyone have any advice or has been through something similar?
