Jessica Alba is using her maternity leave with newborn son Hayes to catch-up on her favourite box sets.

The 'Sin City' star - who is also mother to daughters Honor, nine, and Haven, six - welcomed her baby boy into the world on December 31, 2017.

And it seem she has become addicted to Netflix comedy 'Grace and Frankie' whilst whiling away her time at home nursing the tot.

Jessica shared a picture of herself snuggled up to her four-week-old son on Instagram and wrote: ''Tuesdays/all the days w my Hayes #chillin watching @graceandfrankie-I'm on season 4 and I don't want it to end ? #bingewatching #graceandfrankie#lovethisshow #newbornmom [sic]''

The 36-year-old actress previously shared a picture of herself breastfeeding Hayes.

She wrote: ''Sitting at home- feeding baby boy having all the feels for @shanidardenthx for pampering me -really loved my facial- feeling glowy and hydrated [sic]''

Jessica and Cash are delighted to now have a boy in the family and big sisters Honor and Haven have bonded with their little brother already.

A source shared: ''Cash was rooting for a boy, and they are happy about their little miracle ... Jessica thinks that the process has been much easier so far because she has been a mom for years now. The girls are really excited to have a brother and already obsessed with him.''
