My baby has just turned 5 weeks. A few weeks ago he was managing two stretches of 3-4 hour sleep at night, which was good. Then poor little guy got a stomach bug & it all changed because he was poorly. Now 10 days later he is almost totally better (tummy still slightly unsettled yesterday but he's feeding well & not being sick) but he only sleeps shorter stretches at night - sometimes only an hour, or two hours. Am so tired! He is feeding fine.
