[GRO] Infant/Toddler wont achieve milestones

infants for me have been horrible. I have never been able to achieve the crawl milestone no matter how much time I put into it. But now, since the update released with fairies, when I leave the lot and come home, my infant is across town! I can’t get my sims to go get them. I have to cheat their needs constantly just to keep them from being taken away. The last time they were left across town and off screen, I couldn’t even reset them. So frustrating.
