"Flip or Flop" star Christina Anstead is on bed rest three weeks after the birth of her son with husband Ant Anstead.

Christina, 36, posted a photo with her newborn Hudson from bed, looking weary.

"Welll... I’m a moron. I felt totally fine since one week postpartum- like zero pain... but I was resting and taking it easy ... and then I threw Tay a bday party and was lifting and running around all weekend... and yesterday I woke up like oh crap ... and today oh crap turned into oh sh** - I definitely hurt myself," she wrote on Tuesday.

"I really don't feel comfortable trying to go down that route again."
