What is a good age gap?

Ca

My first born is about to turn 1 in March and we definitely want to give her a sibling somewhat close in age (so they can play together). I always thought we would start trying a little after she's 1, (so they would he 2ish years apart). But I keep going back and forth because I have no idea how I will manage a newborn and a 2 year old! I know it's definitely doable its just hard for me to wrap my head around! Any experienced mom's want to chime in and give their opinion on age gaps?
