When after having a baby can someone undergo gastric bypass surgery or lap band surgery?

3 Months: But why? Diet, exercize, push the baby carriage, avoid significant risks and high return rate?

Band after baby: There is no absolute rule of thumb on this, but i would wait at least 6 months for your body to recover and get back to pre-pregnancy weight before having surgery. Also, taking care of a newborn is a lot of work and you probably want things settle down a bit because you won't want to be up all night with the baby during the first week after surgery.
