Sibling spacing

Hello! My girl is 14 months and now we’re thinking about another baby. Does anyone have experience or advice on a good age gap? I originally thought 2 years but now I’m wondering if a 3 year gap would be better? My girl is super active so I know adding another pregnancy then baby would be hard. We were thinking about trying starting July. That would be 2.5-3.5 age gap depending how long it takes. Any mommas with an age gap like that? Or should we start right away to have them closer?
