I keep getting mildly disapproving comments 
FIL asks if I want a decaff when we go over. I say, oh thanks but I've not had a coffee yet today so might have a regular one. He will check a couple of times with raised eyebrows and last weekend said "right, so x is having tea, y is having decaff and Johnny is having regular coffee as she wants her babies to be up all night."
DM also keeps asking, whenever the twins have anything slightly out of the ordinary wrong or have a shit night, "Have you been drinking coffee?"
I am beginning to feel a bit persecuted
I have one cup a day, mostly instant at home but a couple of times a week a small or med size from a coffee shop.
I even tried giving up caffeine entirely for one week of hell but apart from making me a crabby witch it did nothing.
Please tell me it is normal to drink coffee when bf???!
