Having trouble waking my 4 days old to feed

Hi there!

My milk has come in on day 3. I have been complementing with formula even if my breasts are leaking. It’s been tough. Baby girl doesn’t want to wake up to feed, I’ve tried EVERYTHING. It takes me an hour an a half to nurse her at least 15 minutes if that makes sense she falls asleep within 3/4 minutes of being on my chest.

We’ve been doing skin to skin, diaper change, tickles, water in her face (I wet my finger and wet her a bit to wake her up), blow on her, literally EVERYTHING and still I can’t manage to keep her awake!!!

Any tips? Has anyone been through this?
