Sugarland's Jennifer Nettles Debuts Son Magnus Hamilton—See the Pic!

"In short, this baby is the boss of me," the singer wrote along with a picture of her son on her website

Jennifer Nettles celebrated Mother's Day by giving fans their first glimpse of her 5-month old son, Magnus Hamilton Miller.

In a blog post on her website, the Sugarland singer not only offered up an adorable pic of the little bundle of joy she had with her businessman-husband, Justin Miller, but she also talked about how having a baby has impacted her. For starters, it's changed everything.

"Needless to say, especially to those of you who have children, the rhythm of my life is way different than the movement and pace before baby. In short, this baby is the boss of me," Nettles wrote.

The 38-year-old country star then revealed how she's adapted to the changes.

"You can read every book and website (I've read them all), and listen to the well meaning advice of family and friends, on how to get your baby to, for example, sleep more or through the night," she added. "But guess what? This stuff is not one size fits all. Anyone who tell you it is, lies…and don't get me started on sleep deprivation."

Nettles capped her Sunday by sending fellow moms out there some Mother's Day wishes.

"So much love and joy on my first Mother's Day! A very Happy Mother's Day to all the mamas!" she tweeted.
