DS is a strapping 20 week old and has always loved his milk. Am back at work now and have built up a store of EBM but supplies are running low and I just can't keep up with him - would need to pump 8oz per day and I can't manage it! His appetite is growing, waking up in night to feed - all classic 'gimme food' signs, right? But am worried about weaning at under 5 months and wondering if I should try him on some formula/give up BF and switch to formula as it's more substantial. We have now gone back to feeding every 3 hours, draining each boob each feed and I'm knackered!
