Breastfeeding premie?

Hey moms!! Hope you are all well. Writing live from NICU where I spent past 14 days with our newborn baby girl who is doing amazing.
Baby is breathing on her own and adapting to everything pretty well since birth. She was born 32w + 5d.
I have been pumping (a loooot) since day 1 and have amazing nurses here to teach full time.
Am just curious to know from your experiences ladies if you had babies more or less around 32-33w when did they start suckling ok on their own?
She is really into trying now but it last a couple seconds or so and she tried on and on and gets tired. Oh and much more effective at night too ;)
Dould like yo share with other moms!!!
Thanks a lot!
All love ❤️
