DS is nearly 22mo and still BF at least once between bedtime and breakfast time.
He usually has a BF at bedtime, then maybe twice a week he'll sleep through til 6am ish, the rest of the time he has another BF in the night. I'm generally ok with this, I had kind of hoped he'd give up the night feeds by now but have not wanted to force the issue. He will go to bed without the BF if I'm not around but I've never left him overnight yet.
Next weekend I have arranged to take my 9yo DD to stay for two nights with an old friend of mine who has a similar age DD. Its something I've been promising DD for ages, that we'd go away together, and when I arranged it a few months ago I then proceeded to bury my head about leaving DS 
So now its 5 days away and I am all worried. Should we do a dry run first? I'm guessing I'll need to hand express a bit while away but am assuming my supply is now robust enough to cope with 48 hours off - am I right?
Should add that DS has never shown the slightest interest in milk from a bottle, though we aren't averse to trying again. But then it seems a bit daft to get him to like a bottle at nearly 2, when really I know he can go overnight without milk and have some in a cup during the day.
