Apologies if I seem like a neurotic first-time Mum but I am concerned about 8 week old DD. Today is the second day in a row that she has been sleeping around the clock, including seven hours in one stretch from 11.30pm last night until 6.30am this morning, missing out her night feed. She has had a horrible snotty cold and cough and has been very snuffly which has been quite distressing as she was really struggling to breathe, (we used saline drops and Snufflebabe vapour oil and she slept mainly on our chests so she was upright which helped). She seems much better now in terms of the cold clearing up but absolutely shattered and has awoken mostly just to feed and then nod off again throughout yesterday and today. Should I be anxious or could recovering from a cold leave such a small baby so worn out? Many thanks!
