I get that this is controversial - but for your babies sake please consider breastfeeding if you can, even for six hours then formula afterwards. On a basic level the first six hours are the most important:
‘Colostrum is considered your baby's first immunization because it contains large quantities of an antibody called secretory immunoglobulin A (sIgA). As breastmilk changes from colostrum to mature milk, the concentration of immune factors and antibodies decreases, but the volume of breastmilk greatly increases’
Six hours does that, six days of you can, six weeks even better, six months...etc (reduces the risk of diabetes, cancer, obesity for the baby, reduces risk of breast cancer for both you and a daughter). If your baby is exposed to a virus during the time you breastfeeding - even if you aren’t exposed, then breastfeeding will mean that the requirement for immunity is relayed to you, you create antibodies & your baby is protected.
Worth thinking about unless there is a medical reason not to. If you have time have a read of Dr Jack Newman’s website - breastfeeding doesn’t have to be hard or restrictive. To reduce the risk of SIDS if nothing else is worth a go. If you can’t you can’t, fair enough, but if you can then great, each to their own, but make an informed decision if there isn’t a medical reason not to - there is a lot more money behind marketing for formula (a big money business) than breastfeeding (all free apart from the cake).
Other than that I second the big black pants & a nightie recommendations. Good luck
