The 'Glee' star welcomed her first child, son Josey, with husband Ryan Dorsey in September but joked that breastfeeding has taken a toll on her body.

She wrote on Instagram: "Shout out to my son for the lopsided boobs. LOL #breastfeeding #momlife He is SO worth it (sic)."

Naya previously admitted she was a little hesitant about breastfeeding, explaining: "One minute there's nothing going on with your perfectly perky boobs and the next a nurse is rolling yellow stuff out of your nipple and putting it in your baby's mouth.

"Things like achieving a proper latch, combating engorgement, and practicing different holds soon became my sole priorities. Our bedroom became a haven for all things breast; breast pads, shields, pumps and creams."

However, Naya also revealed that her life "changed forever" when she gave birth to her son and seeing him for the first time took her "breath away".

She shared: "On September 17, at 8:31 a.m., my life changed forever. I went from being pregnant with my first child (for what felt like an eternity) to being a mom!

"Seeing Josey for the first time literally took my breath away. Really, I gasped! It was such a surreal moment to be face to face with my son.

"Looking back on the entire journey feels like a dream that I can't believe I accomplished. And reality set in quickly when they placed him in my arms for the first time. This was my son, to have and to love, cuddle... (sic)"
