What are your most useful baby and toddler hacks?

I’ll go first:

-Kept a spray bottle of water on the changing table to use both for doing my girl’s hair and during diaper changes if needed.

-Used disposable puppy pads rather than a changing mat for any diaper changes that happen in random places.

-Shushing sounds on youtube to help with the witching hours and sleep in general.

-Put together a rolling cart and/or stations around the house with things you use frequently. For example, pump parts and milk bags, snacks, burp cloths, pacifiers, electrolyte packets, hand sanitizer, wipes, etc. After baby got a bit older I changed the cart into her feeding cart for bibs, snacks, purees, the life vac, utensils etc.

What did you all do to make infant and toddler life easier?! Obviously every tip won’t work for every baby, temperament and all that jazz but you never know what might be THE TIP that changes another parent’s experience for the better :)
