I updated the game when the infant update was released, p.s... i took all mods and tray items out of my sims 4 folder while doing so. then when the update was complete i added them all back. I continued on with the game until i wanted a new infant , my sim got pregnant and gave birth fine! When it was the infants birthday and i clicked on the infant to age up, it did not work other than the mother just standing next it cheering and laughing. i continually tried to age it up the same way until it said on the button that the infant was not eligible to age up!! i tried this with 3 different babys to check it wasnt this one and all are doing the same!?
