How much milk do I need to express?

[moodywren]

I have a 5 week old baby and want to express off a feed for my husband to feed him while I have a night off. How much milk will I need to express? Will I need a full bottle?

At 5 weeks old I wouldn't think you'd need more than 4, 5 to be safe. Is so hard to tell with bf babies.
Don't go far though incase he wont have it. Dd2 will not accept a bottle unless she's made absolutely sure nothing else is available and it's not pleasant.
Even at 6 mts now she looks at me with such disgust if I try to get her to have some water from a cup. Am trying to introduce it so I can have a night off.
Have left her 4 times so far without much success.
