twins are great for me. I actually have them and being greedy, I want more. The absolute hardest was the first 6 weeks. After that it got easier. I nursed them and kept them on same schedule which im sure helps. At 16-18 months they started playing together and to this day they're best friends. Mine never fight or argue. Hard to believe , but true. They have conversations and "discuss" a problem if they disagree and
they take turns giving in to the others ideas. they do keep each other busy and make plans for early next morning prior to going to bed at night. They are only 6 so I hope this stays this way, but my experience has been amazing. I'm sure everyone has different experiences. I'm sure whatever decision is made will be what's right for you.
Of course all children are different so who knows what each child will be like. I don't think I could do triplets though.., lol
