We are more concerned with YOU and if you've been cleared by your doctor to resume regular activities (including exercise). If you've delivered vaginally, this is typically at 6 weeks, or 8 weeks if you had a c-section. Once cleared, you can begin classes whenever you're ready!
Children can take classes with you up to any age so long as they still enjoy a ride in the stroller. ALWAYS get your doctor’s permission before starting this or any other kind of exercise program.
