There’s no perfect solution. There’s a lot of research data that says we remember less when we’re taking pictures because we aren’t taking mental pictures at the same time. If there’s something incredible happening just watch. By the time you get your camera/phone in position it will be over, and you’ll have neither the photo nor the mental picture. For situations where you expect there to be good photo-ops ask a friend or someone less central than you to take pics as they see fit and share them, like at birthdays etc. One friend of mine sets her camera up on a shelf facing the room with the action, like the living room at Christmas, and has the camera auto-snap a pic a minute. Biggest thing really is don’t obsess about it because you’ll miss it all worrying. And, once you’re in situations with other people’s kids there will always be someone more intent than you to get pics, so just ask them to share. Try to enjoy things in the moment. The memory of it is better than the pic, even if it fades or changes over time. The photo can be lost anyway. Good luck.
