My baby is not putting on enough weight so I'm having to top up with 30ml formula after each feed. Today he wouldn't stop crying, wouldn't latch on and it just go so frustrating, I gave him 60ml formula instead of breastfeeding him. I just felt so helpless seeing how upset he was getting. Now I'm worrying myself that I've just further reduced my milk supply. Is there anything I can do to undo the damage? I really want to breastfeed but the formula top ups and pumping milk is hard.
