weaning

So, originally Brite had 4 kittens, sadly one passed right after birth. One I lost last week at 5 weeks old, I don't know what happened or why but he jut stopped gaining weight. I tried supplement feeding and had an appt at the vet last Friday but he passed that morning around 5am in my hands...

My girl kitten keeps trying to suckle my boy kitten!! She tries to suckle him all over and I can imagine it's quite uncomfortable for him, any tips on how to get her to stop? And why does she do this still if she's fully weaned? :bored:
