Adorable! Carrie Underwood's husband posts sweet photo of their son Isaiah

We haven't seen much of Carrie Underwood's son Isaiah since he was born in February, but thankfully the singer's husband Mike Fisher decided to let fans see how much his "little man" has grown over the past few months.

Over the weekend, the pro hockey player posted this cute Instagram pic that more than proves what a lucky girl Carrie is.

A sweet son + a hunky husband = #WINNING.
