E ssence Atkins and her husband Jaime Mendez got the best present they could have asked for on Christmas Day — a son. “Found happiness, our first baby, a beautiful healthy boy, was born on Christmas Day!” Essence, star of Are “We There Yet?,” tweeted. It’s the first child for the couple, who were married in September 2009 after meeting on Match.com. Essence had a relatively painless pregnancy up until the last month, she writes. “I’m convinced the last month of pregnancy prepares you for no sleep when the baby arrives. Ugh, I’ve been awake 21 hours,” she tweeted recently.
