When I had babies in the house, I ate all day long. You're not eating because you lack self-control. You are eating because your body needs fuel. Are you breastfeeding? If so, eat. Your body needs these calories. As long as it's not junk, don't beat yourself up over it!
Today, my youngest is 4. I sleep, I workout, I have time to cook. I can take a nap on the couch on a Sunday afternoon and trust the kids won't burn the house down. It gets better, Mama!! Hang in there!
