Teenage mothers are much less likely than older mothers to breastfeed their infants. The lower breastfeeding rate among teenagers aged 16-19, compared with women aged 20-29, is due almost entirely to the fact that teenage mothers tend to have characteristics associated with a lower likelihood of breastfeeding among all women, such as lower educational level, lower income, and being unmarried. Even so, nearly 40% of the difference between teenage mothers aged 15 or less and mothers aged 20-29 remains unexplained by these factors and may be due to developmental aspects of adolescence, such as greater egocentricity and greater concern about body image.
与年龄较大的母亲相比，青少年母亲母乳喂养婴儿的可能性要低得多。16至19岁的青少年与20至29岁的女性相比，母乳喂养率较低，几乎完全是因为青少年母亲往往具有在所有女性中与较低母乳喂养可能性相关的特征，如教育水平较低、收入较低以及未婚。即便如此，15岁及以下的青少年母亲与20至29岁的母亲之间近40%的差异仍无法用这些因素来解释，这可能归因于青春期的发育因素，比如更强的自我中心意识和对身体形象的更多关注。
