He is bottle fed and we are working on weaning. He was sleeping through (food wise anyway!), but has started waking in hunger in the night. It's because he's so excited about what's going on around him that he won't drink more than around 20ml at a time most feeds, and with the amount of food he currently takes in, he needs around a litre a day to sleep through.. Which used to be no problem. I have a toddler so going somewhere quiet for feeds not an option 
. Just a phase we have to wait out or can we do anything?
