I've done my googling and know breastfeeding is quite an effective contraceptive if you're exclusively breastfeeding a baby under 6 months, and your periods haven't returned.
DS is only five weeks and ebf, however also gets expressed breast milk in bottles regularly to give me a break. Can't find much online about the impact on the effectiveness of contraception.
Hope the regular expressing means it still works otherwise we might be looking at a very small age gap
Any thoughts?
