Baby stuff/Stop labelling the first life stage as an object

Most of the time, I forget that the baby is there until they cry or I see the pop up in the corner. I would like if the did add little more gameplay for them.
like
strollers for them so sims and take their babies and toddlers with them as they go for a jog or walk their dogs.
they can get too full or have a little 24hr cold and cry more often and throw up on parents
have tummy time or teach them to crawl
new cribs
small teddy bear they sleep with so they don't get nightmare (for the toddlers too)
