Hilary Duff cant stop smiling since becoming a mum

While sleepless nights, changing dirty nappies and constantly cleaning sick off oneself can make some new mums want to weep a little, it can make others want to smile and it seems Hilary Duff falls into the latter category.

Speaking of her joy at welcoming baby Luca Cruzto the world three weeks ago, Hilary told Life & Style magazine that her little bubba has been making her happy every day.

Motherhood can have its difficulties, but luckily, Luca has been a great baby. 'The past couple of weeks have been the most joyful time. Luca makes us smile all day, every day!

But dont worry mums of the world, it hasnt been completely drama-free for the grinningHilary in fact, shes just as sleep-deprived as she is expected to be, meaning things are running to schedule.

I'm a bit short on sleep, but he has been the best behaved little boy. We are so fortunate to have a strong, healthy and happy baby," she confessed.

Motherhood certainly hasnt stopped the former Disney actress from recording her duties on Twitter though. The 24-year-old has been giving her fans regular updates on little Lucas developments and her own feeding pattern. Just last week she informed them, Luca fed! Mamma fed! Time to do it all again in 2 hours! Oh how life has changed! In such a wonderful way.

Its just all too cute isnt it nice to hear someone be so happy? And just look at Lucas gorgeous little face!

Hilary and husbandMike Comrie welcomed Little Luca to the world on 20 March.
