I buy this for my daughter when she be around 6 month old , and she have sleep with it every night since then . it be small , lightweight , and the perfect size for she little hand . besides be about the cutest thing in the world when you see it tuck underneath she arm while she be sleep , it have also save my hair during nursing session . I always have Sweet Pea available when I nurse , and now instead of pull my hair or scratch my face she hand be busy hold and explore she baby . I do like have the outer pea pod for when we travel or take the baby somewhere because it keep the baby cleaner . my daughter be now 11 month old , and she be so attach to she Sweet Pea , that we buy a second one just in case we need a back-up !
