my 21mnth old dd has started waking up for bottles again through the night, i have posted about this before but she stopped after a couple of wks and it was only once a night now it is atleast twice!! i have tried to not give in and just put her back to sleep but she will not go back over until she has 1 and she does drink the whole thing! i work full time so ive taken to just given her the bottle when she gets up and putting her back to sleep b ut i cant do this forever as im absolutely wrecked! am i not giving her enough of something and thats why she's waking up? i just dont understand why she's waking up obviously hungry!
