So this one is actually for mama, immediately after baby, rather than the lil one himself. The idea of literally shrinking the postpartum belly back to its pre-baby size sounds crazy. But the Belly Bandit does just that. The postpartum compression wrap is worn for six weeks after baby's arrival (day and night) and helps retrain the muscles and shrink the belly back into place. It doesn't sound possible, but as several of us here can attest — it works!
