Bonding 4mo old w/ 4 week old

[Inspector.Guinea]

I have a 4mo old guinea pig (Tiny/Female) and she doesn't get along with my oldest female (Reese). Reese just had a litter of four a few days ago. After 4 weeks I hoping to bond at least one of the pups with Tiny. I've let Tiny "sniff" one of the pups and she tried to climb on top of it? Any advice on bonding the pups with Tiny?

Hi and welcome

Please double-check the genders of any piggies you are bonding, just to be on the safe side. Mis-sexing is sadly anything but uncommon.

Mounting is a mild dominance behaviour in both genders and not just a sexual behaviour.
