the litter was three weeks yesterday and seem to be hungry every three hours still. All are two and a half to three pounds so they are not starving but I wonder if mom is making enough as they seem to want more after being on her. When is it too early to start them on a regular basis with food? The last two night I've made then goats milk and baby cereal and they love it but how often should I do that at this age??? Thanks in advance for the advice!
