Three sets of twins! Oh my... that is quite an adventure and a half!
Organising and scheduling was my go-to for keeping sane with two sets of multiples. I made sure to assign a specific colour to each twin - green for A, and yellow for B - which helped us quickly identify them, especially when they were so tiny and looked so similar. It also helped us avoid accidentally switching their names, which happened more often than we'd like to admit! Their clothing, bed sheets, even the nursery decorations had these colours incorporated, which made things easier.
We established a strict feeding and changing routine, on the hour, every hour, that we stuck to religiously. It was meticulous, but it helped us keep on top of their needs and our sanity. We also implemented a system where one parent would take the left side of the room for one feeding/changing cycle, and the other parent would take the right, so we each had 'our' twins for that session. This way, we got to bond with each kiddo individually and learn their unique traits beyond just their eating and pooping habits!
Outings... yeah, those were interesting. We quickly learned that the best approach was military-like precision in our planning and execution. Having an exit strategy, or two, also became crucial. Sometimes, you just gotta run that errand or attend that appointment and hope for the best. For us, having a double stroller with a fold-out bench seat came in handy for quick cafe visits - it gave the kids a safe spot to sit while we'd quickly enjoy a coffee. Otherwise, we'd have family and friends join us for support when heading out. The more hands, the merrier!
Keep track of your health, too. Having three sets of twins is physically demanding and exhausting. Make sure you're getting adequate rest, nutrition, and support, because looking after yourself will help you look after them better. Don't be afraid to ask for help either; cooking, cleaning, or babysitting - it all helps!
Lastly, enjoy the chaos and the craziness. They grow up fast, and before you know it, your multiples will be unidentical individuals with unique personalities. Cherish the special bond they'll share.
Best of luck!
