My 5 and a half week old baby is usually pretty easy but the last few days she's been really unsettled. She's struggling to sleep (lots of yawns but crying and not drifting off), wanting to feed all the time (she's ebf) crying constantly when not feeding (that's the only thing I can do to settle her) she won't settle or sleep in the sling any more. Also she's been sick a few times, not much but she never used to be. Could it be reflux? Or I've read looked at wonder weeks and thought it could be a growth spurt, or possibly over tiredness as she has just started to be really alert and looking around at everything (inbetween crying!)
Is this normal and any suggestions of what to do? I feel unable to help her other than by putting her on the boob, which is exhausting. She's currently on my shoulder crying and screaming, then looking sleepy then screaming again!
