My little one is 14 weeks and had been sleeping through from about 8 weeks (9ish until 7/8). She now goes down between 7/8 and wakens for a bottle between 5/6 when she will usually sleep until 7/8 again. The only difference is that she now wakens during the night a number of times, no interest in a bottle and will usually be soothed off to sleep again. Is this normal for her age?
