I worked 40+ hrs a wk from when my daughter was 5 wks old and on, she is now 5. She is definitely a mommy's girl. It's ok to work full time as long as the time you spend with your little one is quality time. She is always my lil helper with anything i do, so that makes us closer and shows her responsibility.
Honestly, for the first 3 years of my sons life my now hubby( also his father) and I had issues and I lived on my own with my son and worked a 40 hr work week. He's 5 now, and is the ultimate mommy's boy!! I wouldn't have it any other way!!
