Skiddo and Gogoat can learn Milk Drink I learned, but I also found out that even males of the species can learn it. I think this move should be limited to females of those Pokemon.
While we're at it, all mammalian Pokemon part of evolutionary lines that have members that can breed should learn the move as a TM as long as they are female, with an added bonus - if said Pokemon knows the move and has mothered another Pokemon, she can heal her offspring with the move outside of battle, analogous to a mother mammal feeding her milk to her young.
Adding on to this, when a mother mammalian Pokemon heals her offspring with Milk Drink, it would raise the offspring's happiness
