drinking when bf

hi girls, hope ur all well,

my baby is due 16th nov and im planning on bf. im just wondering how much you can drink when bf as it is my sisters 18th and she is having a party on the 19th dec. ive read u r ok to have a glass or 2 of wine but im not really a wine drinker, wud rather drink lager and blackcurrant or whiskey and lemonade. does the same apply to these drinks?? or will i be best to just stick to soft drinks at the party??

(it is also my bday the day before the party so was gonna combine my bday treat with sisters party lol)

thanks Genna
