This is Krishna as a toddler, lying on his back and sucking his big toe. The form with a leaf attached at the back is called Vatapatrasai (Vata refers to Indian Fig and Patra is leaf). For more information on Vatapatrasai please see one of my earlier blogs.

The one without the leaf is sometimes referred to as Santana Gopala. That is where its gets interesting.

There are three other iconographic forms of Santana Gopala.

In Kerala, the form of Vishnu holding a child in his cupped hands is worshipped as Santana Gopala. Try searching for Chenganacherry temple. There is a long story about this form, involving Vishnu and Arjuna, and that is reserved for another blog.

Sritattvanidhi identifies the suckling Krishna (along with Yasodha) as Santana Gopala. An example from the Met Museum is included here for reference.

Silparatna refers to Krishna as an young boy ‘with a pot of butter under his left arm and eating out of a ball of butter placed in the palm of right hand’ as Santana Gopala.

It is quite likely this above form,Vatapatrasai(?), is worshipped also for obtaining the boon of children and hence he is called Santana Gopala (Santana means offspring). The name, Santana Gopala, when applied to this case is more related to the function rather than the form.

Given that iconography of these two Vigrahas are closer as compared to other Santana Gopala examples, I prefer to refer to the toe-sucking Krishna without fig leaf as Vatapatrasai.

The brass one is from Karnataka and I have no suggestions on the other one, though the crown is trying to tell us something.

These two are probably about 150-200 years old. They are about 8 cm in length.
