Vanessa Lachey has taken to sharing her journey through motherhood with fans on her personal site, VanessaLachey.com.

Recently, the mother of 4-month-old son Camden with husband Nick Lachey blogged about one aspect of being a new mom that caught her by surprise. The 32-year-old wrote:

“It is amazing how much time a little munchkin takes up. And when he’s not taking my time, I am either sleeping or eating, then sleeping again. They tell you how much sleep you lose, but they don’t tell you why!!!

Now I know…. BREASTFEEDING! It literally is a 24-hour job! It’s unbelievable how often they eat, and for how long.”

Vanessa Lachey continued, “Afterwards, you soothe your infant back to sleep after a diaper change and burping session. And then in just one blink, you have to wake baby up and start ALL over!”

All the same, the first-time mom wouldn’t trade the up-all-night hours.

“It’s sooo worth it,” Camden’s mother admitted, adding, “when you look down and see their little face. Even when they smile that ‘I have gas’ smile, I pretend Camden is smiling at me saying, ‘I Love you, Mom! And thanks for the grub! I know it’s hard work.’”
