Hi,

Neither cows milk formula or or goats milk formula will be suitable. a large proportion of babies intolerant of cows milk formula are intolerant of soy. Your little one is 8 weeks old? With a bit of know how, most mums can learn to express. Tell me, what pump are you using?
The other thing to keep in mind is that things won't be like this forever. Already, just because he feeds every 2 hours when you are there, doesn't mean he couldn't go longer. Have you tried going our for a while without him now? You could get a long way in 2 hours (get your haircut at least) See how it goes
