13month still not sleep through the night

hi Mummy i facing same issue with my no 4 only now 14 mths. my baby cannot sleep without latch on. worse still, she does not suck milk bottle instead she prefer to drink using straw. if she cannot gets nipple she will scream. i remember my helper told me that her friend from opposite block can hear her crying. what i do to stop, i ask my helper to sleep with my baby. it works 80%. at times she still crying loudly for nipples and that is where i have no choice but to give her latch on. but again, i never stop i keep trying letting my helper sleep with her and now getting better. can sleep as early as 945 and wake up 1 or 2 times just to drink water no milk.
