Yes, it's totally fine. My baby is almost the same age as his 2 cousins and they are all exclusively breastfed now. When they were newborns I used to breastfeed my niece since her mom's milk is very limited and her nipples are inverted. After trying everything, from herbal teas and juices to malunggay capsules and expensive breast pump, she was able to increase her milk and sometimes I even ask for some of her stored milk for my baby. 😄 When I ask her which is the most effective she said nothing really worked, it's just the law of suppy and demand.
Breastfeed no.. It is a very personal bond.. I wouldn't want baby to mistaken her as the mother
