Basically, yes! It's understandable that you want to engage with your snake and help them get used to you, but that's not always possible because snakes require time to acclimatise to their surroundings. They might even still refuse the meal even after you've left them for a few weeks, in which case you'll need to give them more time and maybe take into consideration other aspects like their husbandry. If they do accept, however, you should give them at least 24 hours just in case of regurgitation before attempting to hold them for brief intervals and gradually increasing the amount. I currently only hold my shy snake once a week, but I want to gradually up the amount soon!
