@grace4us Our oldest is 4 and our twins are a little over 2. The extra toddler adds some complication, but things didn't start feeling manageable for one adult pretty regularly until after the twins were 18 months old. Even then, it's not always that things are easier, they're just different. We've got friends With twins that are now in high school and they told us multiple times that the magic age for things really easing up was around 4 years old. Based on where things sit with our oldest, that feels very reasonable.
There are definitely moments now where everyone plays together nicely, but it takes a long time for toddlers to understand regular kind play with one another and sharing.
Don't be overly self critical, raising multiples is an incredible challenge that no one else gets. Parenting is relentless already and doing it with multiples is dialing it up to extra difficult. If you can carve out some predictable time for self care, even if it's just 30 minutes 5 or more days a week, that went a long way to keeping things positive for my partner and I.
The first 7 weeks were the hardest time that we've ever been through in our lives, but the improvement was so gradual, we often lost track of what had become "easier" than it used to be. You've already accomplished so much getting to this point, and you'll get to some really fun milestones soon that help with the parent child bonding immensely!
