DD is 12 days old and for various reasons am having to top up bf with formula cup feeds. Despite feeling like all I do is have DD on me, I dont feel like I am keeping up with the demand, in one boob DD doesn't latch as well and expressing from that 1 shows it doesn't have as much as the other 1. MW suggested tigers milk ( full fat milk, bananas and brewers yeast all mixed together) to boost supply. Has anyone tried it? Does it work?
