That's okay! Sometimes babies cry. You will be in a group full of moms with their kids - we've all been there and we all get it. Absolutely no judgement from anyone!
You're always able to do what you need to do to take care of your little one and, of course, we try to keep things moving so that the kids are happy and entertained. If you need to change, nurse or console your baby, please do so. Don't be surprised, if your instructor offers to push your stroller or hold your baby because they know sometimes you just need a minute to take care of yourself.
