At what point do I need to supplement my newborn with formula milk?

There are of course a lot of associated biological benefits of breastfeeding for the mum. Among these is the earlier return to pre-pregnancy weight, your body increases production of serotonin which facilitates a quicker and deeper level of sleep, breastfeeding for two months improves mother’s systemic and emotional health; exclusive breastfeeding on-demand, day and night provides 98% effective contraception for six months; not to mention of course the reduced household expenditure from cost of formula as well as out-of-pocket costs for childhood illness. There are also continuing research between breastfeeding and reduced rates of female cancers.
