Yes the first few months' blitz of feeding, changing, and rocking can really put your endurance to the test! Establishing a routine, or at least figuring out what works, is crucial for maintaining some sanity, haha.
Many parents often ask how one can possibly distinguish between two babies, especially when they're brand new. But somehow, that instinct kicks in, and you'll know which baby is which, even though they look identical! I remember having to learn to be super organized and label everything clearly - bottle bags for each baby and color-code them, haha!
I found it helpful to set up a system for essential items like bottles, pacifiers, and small toys, so they're easy to find and grab when needed. And as your babies grow older, you'll need help keeping track of whose clothes/toys are whose, especially when they start talking and asserting their independence!
Speaking of help, it's good that you're aware that you won't be able to do everything by yourself. It took me some time to learn to accept help, but having an extra pair of hands can be a lifesaver, be it holding a fussy baby for you to take a quick shower or helping with the dishes. Don't hesitate to reach out to your partner, family members, or friends!
Also, I'm sure you've probably heard this before, but do keep a sleep schedule for yourself. When the babies are napping, try to catch some z's too, even if it's just lying down and closing your eyes for relaxation. It really helps to have that reserves of energy stored up, especially when one or both decide they want some extra cuddles or need attention in the middle of the night!
Last but not least, enjoy the ride and try not to stress too much; it's such a cliche, but time really does fly. Before you know it, your twins will be running around and having their own little conversations. Enjoy the uniqueness of this special bond they'll share!
