Hilaria explained she had to change the infant’s clothing before they left the hospital for home because he had an accident early on.
‘He peed on his first going home outfit,’ she said in her caption. ‘So we changed.’
She explained on Instagram Stories that her children already met the newborn on Facetime.
It’s not yet know if the couple, who suffered two miscarriages before welcoming little Eduardo, will try to get pregnant again.
They have publicly stated that they really want a second daughter and will continue trying until that happens.
