The 24-year-old actress gave birth to her first child, son Luca Cruz Comrie on March 20. Since his birth Duff has been open about just how joyous she is over her new bundle of joy, saying she and Mike Comrie feel like the luckiest parents in the world.

I cant believe I have a baby she wrote on Twitter, the most wonderful, sweet, adorable baby!

While shes traded beauty sleep for bottles and sleepless nights, she wouldnt have it any other way. On Monday, she returned to Twitter to express just how much different and wonderful her life is now.

Luca fed! Mamma fed! Time to do it all again in 2 hours! Oh how life has changed! Lol In such a wonderful way :) she wrote, adding later on, 4 am...Sleepy eyed. Feeding baby..whew this job is no joke!

Duff, who married recently retired hockey player Mike Comrie in 2010, said during her pregnancy that she had big plans to put out an album and tour after baby, she just wants to enjoy being a mother first.

"I think that after I have the baby I'll want to sit still for a few months and learn how to be a really good mom, " she said in October. "And then there's no reason why I can't put a record out and tour...It might take a little while but I'm really excited about it."

For now, Duff, who saw herself as being an extremely overprotective mother, is enjoying being mother to her beautiful boy.
