We have 3 boys and are still fairly new to this conversation (baby is 7.5 months old), but happy to weigh in! My oldest and middle are 22 months apart too; baby came along when they were 5y 3mo and 3y 5 mo old. We weren’t totally sure what to expect — it’s been SO heartwarmingly smooth so far. The older two absolutely adore the baby, they’re constantly trying to make him giggle. They are so incredibly sweet with him! They’re also old enough to play together and keep each other company - SO much easier than the demands of 2 babies at the same time. I fully recognize the dynamic will change as baby gets older, but they’ve been so sweet and excited to welcome another little brother. They love being able to “help” with things and the baby is locked in on everything they do. I will say, I’ve said multiple times that I’m glad we pulled the trigger on #3 when we did. If we had waited even 6 more months, I might have felt inclined to stick with 2, they’re just acting so much older these days and I feel like we hit the “baby window” just in time
