Molly Sims thinks motherhood is ''amazing and hard''.

The 39-year-old model and actress has introduced her two-month-old son Brooks Alan Stuber to the world via her personal website and has revealed looking after the adorable infant has highs and lows.

Molly explained: ''My first seven weeks as a mama have been both amazing and hard.''

''There's a lot of sleep deprivation involved, but I guess that comes with the territory! Brooks has been sleeping in two-and-a-half to three-and-a-half hour shifts, so I've been learning to nap when he naps.''

However the blonde beauty - who wed producer Scott Stuber in September 2011- confessed her son more than makes up for it by being so cute because the new parents have become obsessed with dressing him up.

Molly wrote: ''Scott and I love dressing him up in all the cute little outfits he has - sometimes he ends up wearing three different outfits in a day - and blue and green are definitely his colors.''

The proud mother also admitted The Feeling she had when she first held baby Brooks after giving birth was indescribable.

The 'Yes Man' actress gushed: ''I think that no matter how prepared you are - no matter how many hours you spend researching strollers, stocking up on organic baby food, and decorating the nursery - there's simply nothing that can prepare you for the feeling that comes with holding your baby for the first time.''
