Baby dreamtime, if someone knew how to to work out when AF would return they'd make a lot of money!! But there are some things that we know can make a difference. It is less likely for AF to return during the first 6 months when babies are exclusively breastfed. From 6 months, when solids are introduced, any solids will replace breastmilk, so the amount of milk the girls need will be reduced. This will increase the chances of AF returning. Not feeding at night is also another thing that increases the chances of AF returning, so once the girl's start sleeping through this will give you a better chance, if AF hasn't already returned after the 6 month mark. The girls might be a little young for night weaning yet, but it might not be too far off for you. Of course none of this is a guarantee - AF returned for me after 7 months with DS1 who didn't feed in the night, and at 6 months with DS2 who did!!

All the best hun.
