I don’t believe either of them are cappuccino.
Mum is a partial pin red harlequin possibly has Dal spots
Dad looks to be a low expression pin dash, dalmation. He doesn’t have the dark to white tail it the v so not likely a cappuccino. I can’t comment on lavender unless you have a fired up pic of him also. He doesn’t have markings on limbs so not harlequin, however this might show up in fired up pic of him, but I think it might be part of the Snowflake trait.
Baby - although has a slight v, it doesn’t have the dark to white section on tail. I’d say he/she is a pin dash brindle with portholes & Dal spots.
I may be slightly wrong, see what ghoulish Cresties has to say. But would be better with fired up pics to confirm.
Tbh, I think I’m order to confirm his a cappuccino, you’d need to pair him to another cappuccino. Or he produces a distinctive cap. But none of these pics show cappuccino (in my opinion)
Also, what is that red mark on the babies back?
