When they’re older

Anyone else wonder what things will be like as the babies get older? How will they deal with things like teething, sleep regression, crawling, walking, feeding solids, temper tantrums. I’m so curious as to what kind of parents they’re going to be…if they’ll put their babies in classes, play dates, go to the park… will they be actively engaging with them? How will they discipline? I’m super nervous as to what’s to come based on the way things are now.
