I'm so tired
DS is 5 months next week and sleep is slowly going to pot. He has generally been ok, past few months down between 7-8 (sometimes have to go in to resettle) and feeding about 12 and 3/4am. Suddenly he is waking every couple of hours then at 2-3 has suddenly been wide awake and being very loud in cot which escalates to crying after a while. I try to feed him (ebf) and sometimes works but increasingly not, doesn't seem that hungry more that he is just wide awake. He is in our room and I'm bloody knackered. Coupled with 2.5 yo DD waking for various reasons I reckon I'm averaging about 2-3 broken hours a night and I'm feeling quite ill during the day and tearful. Is this the wretched 4 month sleep regression everyone talks about come late? What can i do? I've forgotten everything from DD...I know there are no fixes anyone can give me, I guess I am just looking for reassurance, or even just 'I know how you feel'!!!
