Chrissy Teigen didn't plan for this, but she's now doubled up on her breastfeeding duties to appease her oldest child ... but it's not what you think.
Chrissy just shared a hilarious photo of herself breastfeeding her baby son, Miles ... but surprisingly, there's another baby in the mix too.
She says, "Luna making me feed her babydoll so I guess I have twins now."
Wonder how long she's going to have to keep this up ...
As we reported ... Chrissy and John Legend welcomed baby #2 in May and named him Miles Theodore Stephens. Clearly, Luna's not letting him get all the attention.
