I have been invited out oct. 4th for 2 peoples birthdays but am unsure if it's too soon. Apart from the fact I am going to hate leaving DS, is it too soon to be leaving him and using a bottle? (DS1 was fed EBM for first week but that wasn't optional). I never go out, last time was their birthday last year (!) so am kinda keen to go, but am not sure it's fair on DS yet...
