My baby girl is just over 3 months old and up until now has pretty well much slept through the night, however, for the past 5 nights she has suddenly needed 2 feeds during the night that she never used to. Is this just a 'growth spurt'? and is she likely to go back to sleeping through or is my milk maybe not enough for her (I am soley breastfeeding). Other than this, she is a happy baby and still has her 3 or so sleeps through the day which she always has. I don't let her sleep for too long during the day, but rarely disturb her as an hour is usually all she wants (or less). Can anyone advise?
