I've just tried to explain to a 6.5 month old baby that I need a five minute break or my questionable sanity will be non-existent! Today I have reached the edge

I'm tired as my normal STTN baby has had me up from 3 the past two days, and refused to go back to sleep til 9 in the evening unless she's cuddled. I know this is the norm for some of you, but I'm not used to it at all. If I'm tired then my diabetes plays up, which makes me feel worse.
Hating myself as I'm taking the tiredness out on LO by being grumpy and not wanting to interact with her unless I have to
Re: Losing the plot
I also suggest talking to your pedi not because there is an issue but to reassure yourself that this is normal and can happen. The more you realize it is expected from a baby the less it will annoy you and help you be better prepared.
Every time I put her down on the floor for a few mins she goes ballistic after two mins, and I'm finding the sound of her whinging is like lighting a fuse at the moment. If she would just have a half hours nap somewhere other than on me I would feel so much more relaxed and she'd be less grumpy!
Fortunately I'm not back working til Nov 1st, but then it's a WFH deal...not quite sure how I'm actually going to get any work done, I've told my other half he'll have to be trained up so he can help me out in the evenings!
