vroc I read your post during a middle of the night feed then had dreams about Star Wars
great outfit!
Thanks for the formula tips, the perfect prep sounds, well, perfect! There's no mention of sterilising the powder on the boxes here though so now feeling a bit guilty that we've just been using non boiled tap water 
time you poor thing, it's hard enough to deal with sleep issues or feeding issues but to have them both must be hell. You're doing a fantastic job and it's really insensitive of your in laws to say those things. If she's 6 weeks corrected then fussiness is supposed to peak at 6 weeks ish, and she will get her night/day corrected eventually. I really hope for you that it gets better soon. Good suggestion from purple re HV observing a feed
Your situation sounds very similar to a mum in my group, though she is BF and her baby won't take a bottle. She feeds every 45 mins and never naps in the day, is a v slow weight gainer and the mum is at her wit's end after 8 weeks without sleep. The only consolation is that our teacher told her that it means the baby is super alert/has heightened senses and will most likely be very intelligent when she's older :)
You've probably tried everything re sleeping and settling her, but I go through the 5 S's - swaddle, suck (dummy), swing, shush (I use a white noise app for this) and side/stomach position (eg over your shoulder or lap, on your chest). I normally need to use at least 4 of these before DD settles. Or having her in a sling/carrier works and is good for her reflux as she sleeps upright
Ah Q I would have been so mad!! How do people think that's okay???! I hope you told her to mind her own
