Many parents swaddle their infants to promote sleep and reduce night-waking, however lack of definitive evidence about the pros and cons of swaddling when breastfeeding hinders postnatal recommendations regarding this infant care practice. This review critically examines research conducted on the impact of swaddling upon breastfeeding.
Only two recent studies on swaddling outcomes have reported infant feed-type, therefore the purpose of this paper is to consider the known effects of swaddling on breastfeeding babies and their mothers. We interpret the existing literature on swaddling in terms of impact on breastfeeding physiology and behaviour during the immediate post-natal period, and as infancy progresses.
Infants swaddled immediately after birth show a delay in initial breastfeeding, less successful suckling at the breast, reduced intake of breastmilk and greater weight loss compared to un-swaddled babies. Swaddling visually obscures feeding cues and reduces crying, thereby eliminating two key feeding prompts typically used by parents/carers.
As swaddled babies cry less, and are fed less frequently than un-swaddled babies some clinical trials position swaddling as a 'novel weight regulation tool' to combat obesity. However, in the case of breastfed babies, by reducing feed frequency swaddling may impede maternal milk production and thereby infant growth.
许多父母会襁褓婴儿以促进睡眠和减少夜间醒来,但由于缺乏关于襁褓对母乳喂养影响的明确证据,阻碍了产后对这种婴儿护理实践的建议。本综述批判性地审查了关于襁褓对母乳喂养影响的研究。
只有两项关于襁褓结果的最新研究报告了婴儿的喂养类型,因此本文的目的是考虑襁褓对母乳喂养婴儿及其母亲的已知影响。我们根据对产后即刻母乳喂养生理和行为的影响,以及婴儿成长过程中的影响,来解释襁褓的现有文献。
与未襁褓的婴儿相比,出生后立即襁褓的婴儿会延迟初次母乳喂养,吮吸乳房的成功率较低,母乳摄入量减少,体重减轻更多。襁褓从视觉上遮挡了喂养提示,并减少了哭泣,从而消除了父母/照顾者通常使用的两个关键喂养提示。
由于襁褓中的婴儿比未襁褓的婴儿哭泣较少,并且喂养频率较低,因此一些临床试验将襁褓作为一种“新的体重调节工具”来对抗肥胖。然而,对于母乳喂养的婴儿来说,通过减少喂养频率,襁褓可能会阻碍母亲的乳汁分泌,从而影响婴儿的生长。
