Lots of questions

I had my little princess 6 days ago

She was a month early

She’s struggling to latch but we are working on that and I’m pumping

But my questions are

Is it normal to still be getting just colostrum after 6 days?

Is it normal that one boobs produces double the other?

My right boob is hard and lumpy so I’m assuming my milk is coming in.. but my left isn’t.. do both boobs start producing milk at the same time? Or can one produce colostrum still while the other is milk?

Also any tips for premies to latch? She spent the first 4 days in the nicu so we didn’t get a ton of breast time. She gets the nipple in her mouth, and sucks like twice and then stops or goes to sleep.

She’s premie, a month early but she’s also 8lbs 3oz so it’s not like she’s not strong enough to get it, I don’t think.
