Had a bad day at work per chance Debi? 
{{{Becaroo}}} you are not a bad mummy, you just need some help, there is no shame in that.
Pacita - green poo's are a sign of too much foremilk. Don't panic though, it can be easy to rectify and it's not causing any damage to Ines - although I think it may be a reason why she is windy.
When you say she feeds a lot, could it be that she is actually having lots of little feeds, or falling asleep quite quickly into a feed then waking up hungry an hour or so later?
If that's the case she might not be accessing so much of the hindmilk (the higher calorie part of the milk). Which means you then go in circles, she's getting the foremilk (often referred to as the thirst quencher), just about satisying herself with that, then waking up hungry an hour or so later because she hasn't had a full feed.
There are a few tricks to overcome this, from memory:
Keep them cool when feeding - they are less likely to fall asleep. Also feed one side, wake them up with a nappy change, then feed the other side. Tickle her feet, under her chin, talk, sing to her etc etc.
Switch feeding - switch sides every five minutes until the feed comes to an end. This will give multiple let downs during the feed (this keeps the baby interested as lots of gain for not so much work.) Remember that each let down DOES NOT mean your breast reverts to foremilk each time.
Think of your supply as a hot tap, starts of cold (foremilk), gets warmer (combination of the two), then hot (hindmilk). It's obviously rather more complex than tis analogy, but hopefully you get what I mean!!
debs - M is still in a cot. Luckily it's a cotbed so it's more than big enough. It will stay with the bars on until he trys to climb out of it. I still can't believe he hasn't tried to escape, because he easily could!
