Sore eyes and headache from lack os sleep. 10w pp

Ca

Ten weeks pp and I had the worst eye ball pain and headache... Anyone else experiencing this?

Baby naps maybe 4 x 30min a day and has a night sleep from about 7.30pm till 11pm or 11.30pm then up every 1.5h there after till 8am then he is awake. He feed every 2.3h or 1.5h depending..

Any advice for solo mom?
