Liev & Sasha: Mother's Day Men

Naomi Watts and Liev Schreiber took their 21-month-old son Sasha and the family dog to the park on Mother's Day Sunday. Little brother Sammy, who turns 5 months on Wednesday, wasn't with the trio.

The X-Men Origins: Wolverine star recently commented on the lack of sleep in the Watts-Schreiber household. "Now, we have a new four-and-a-half-month-old, Samuel Kai. Our older son is just learning to sleep through the night, but Kai hasn't gotten there yet. So on his bad nights, he wakes up his big brother and it gets a little complicated."

We hope Naomi got in a nap on Mother's Day!
