My baby isn't sleeping well (waking every 1-2 hours and difficult to put down after waking, she is almost 17 weeks) at the moment and I've had some days where I've been feeling really pissed off and fed up and tearful. I have even had a few arguments with my partner which is rubbish.
I talk to my mum a lot about how I'm feeling and today I was talking to her and she said I should introduce a bottle of formula at night because it will help her sleep (this isn't the first time she has said this, she's said it since my baby was born a few times).
I said, I don't think that it will mum, she is waking for comfort as well as food. From what I have read sleep is developmental.
She said that it categorically will help my baby sleep through and she's been told this by loads of people. I said who and she said, just people in life that I won't know 
I'm a first time mum but I just have a sneaking feeling that this is nonsense and I want her support without her pushing this sort of thinking on me (I have told her this). It's really unhelpful and it's actually making me consider doing it (I'm very tired) even though I don't think it's the right thing for us.
AIBU to be upset with my mum for repeatedly suggestion formula?
Or is she right, did it help you baby sleep and it should be considered?
