I have been pretty jammy with my older two dcs, who slept well and I didn't need to return to work til they were both 1 year plus. however have recently returned to work after having DC3, and on his 9month 'birthday' and am struggling. He is teething/has been full of cold, and sleeping really badly, plus waking up for the day pre dawn. I work in a professional job and was almost hallucinating at my desk this week from tiredness. I have to work financially and can't cut my hours as already work part time. Not sure if anyone can really advise, maybe just needed a moan!
