Peta that is wonderful news!! You got some great advice here from the girls, I just wanted to say that if you are in doubt to please ask the people who will support you with educated information. A lot of people just say "well put them on formula" which is very unhelpful and can make you feel like there is NO other option.

Also BF babies DONT gain weight as quickly as formula fed babies. Keep that in mind. Yes 30g is probably not ideal, but it doesn't mean you have to formula feed straight away. There are always other options, like you have discovered here

Good luck and I hope bub puts on some more weight and continues to thrive. You are doing a wonderful job!
