Hey moms,
I am currently due 12/22 with my 1st child & will be exclusively breastfeeding and/or pumping....... just wondering how you all keep track of the times of feedings, soiled diapers, naps etc? Do you keep track the original way with paper & pen or are there any apps you'd suggest? Thanks a lot ladies 😊
