Bottle advice

Antonia • 09/06/2019 and 14/02/2023

I need to leave my little one overnight due to a commiment I cant get out of, he is EBF and absolutely refuses a bottle no matter how much weve tried, he will be 6 months by the time I need to leave him and have already been approved to try him with purees until hes 6 months old, dont want any comments on the purees my question is how long did it take your little ones to use a sippy cup or straw bottle?
