You carry a (newborn) baby/ twin in the Minimonkey TWIN in an upright position on your belly, with his or her bottom low and thighs higher and spread wide; also referred to as the M-Position or Frog Position. Experts recommend this ergonomic position for carrying babies because it can have a positive effect on the development of their hips. The Minimonkey TWIN is a ‘hip-healthy product’, certified by the International Hip Dysplasia Institute.
