If you're not comfortable about it, let them know po. Breastfeeding is a very special and intimate bonding activity for mother and child. Personally, I think magseselos ako since it's the only thing that's supposedly only I can do for my baby ☺️ But as far as baby is concerned, there shouldn't be any problem. It's also highly possible na mag(re)lactate rin sila kung patuloy ang paglatch sa kanila ni baby. In which case, will be highly beneficial for baby.
