Currently so incredibly tired. DS3 is almost 11months. No such a great sleeper in the early days but had improved. We were away for a few weeks over Christmas so he was in our room in a travel cot staying with family so things went a little backward then.
When we got back sleep improved and I was reducing BF at night (down to 1 quick feed at 3/4ish and sleeping 7-7)
Now winter bugs have set in. He’s had a temp every week (with breaks in between). Last week has been terrible for sleep. Waking every 45 mins, really upset and doesn’t want to be awake. Initially was settled with a quick cuddle but now has conjunctivitis so eyes needs a clean. Took him to GP yesterday, nasty virus etc..
Typically I’m back at work this week. I work shifts, nights etc. He was taking a bottle but now refusing. DH runs his own business so not coping with the lack of sleep. I usually end up sleeping in spare room with DS3 so he’s not directly disturbed but obviously hears him.
DS1&2 are school age and doing the best they can. Behaviour can be typical brothers challenging behaviour but I’m not helping by being less tolerant than usual.
Feeling a bit like it’s never ending. Please tell me I’m not alone and ideas that helped you survive! 
No family close by. Great friends who have helped with school run and clubs though.
