Nobody is thanking the m for feeding their kid for gods sake
Breastfeeding often comes with a set of bodily challenges including but not restricted to broken skin flesh and leaking blood as many on this thread are aware of even if they fed formula
Breastfeeding also encounters a lack of family support in a country where many families have very few breastfeeding generations to offer useful advice
Breastfeeding in public only became a part of law in 2010 and no - it's still not acceptable in very many places. Women do feel nervous
Breastfeeding involves exposing even if briefly what many would consider a private body part
So - someone thought it's nice to show a nervous fellow breastfeeding mum some support from an kind stranger. That's okay.
If it's twee for some that's okay too
If a bottle feeding mum wishes to do the same to another mum that's okay too
