a day.
Unfortunately the only advice I have is wait longer. I think we tried too early with my daughter and it didn’t go well.
Have you done a sticker chart for successes? She gets to put a sticker on the chart and when she gets to 4 or 5 she gets a treat?
Or we did an empty jar and she got to fill it up with little fluffy balls and when she put one in she got a skittle.
Also, lots of apple juice to help get it flowing.
