@Exitstrategist I had trouble with weight loss too. 3.65kg at birth and was 3.185 at day 9. Suggested to top up with formula too by health nurse after that mornings weigh in. That same afternoon I had appointment with a lactation consultant who wasn't happy about weight and his jaundice so we ended up back in hospital.
On hospital advice we topped with formula due to the weight issue.
I had great trouble feeding to start with as he chewed me to pieces and just fell asleep when feeding so this more than likely contributed to the weight issue. He has always been quite lazy on the breast though I feel (compared to how his sister was previously) and will just go to sleep despite attempts to encourage him. I'm guessing now that might be an effect of having bottles too.
I am still feeding (both with and without a nipple shield as he still makes me a but sore) and topping with a bottle if needed. Health nurse has me on some meds to boost milk supply which I think they have a bit. I'm also having to pump to stimulate supply too. Feel like feeding time is such a log drawn out process with breastfeed, bottle if need be and then pumping. Am a bit over it really. I let him have plenty of time at the breast so am still rather tender. Evenings are the worst as it's like there's nothing left (I know this is normal) but he'll just scream if I don't give him a bottle, but I honestly can't keep him on there longer or my nips will legit fall off.
Anyway, sorry that's a long waffle. If you feel she is feeding well and latched properly and seems satisfied with feeds then I would see how she goes for a bit longer., but obviously not at a detriment to her health. It's a tricky one... I've made peace with myself now where I'm happy to feed him, but if in the long term there is a switch to bottles then so be it.
On another note, does anyone have a baby that absolutely hates having their nappy changed? Nate screams blue murder every time! You'd think he'd get with the program by now, but nope. He has a bit of nappy rash at the mo so that's definitely not helping, but it's such a traumatic process each and every time poor love 😔
