Baby ate too much purée

AB

My niece was babysitting my 6 months old today and I told her to feed him butter squash purée. She didn’t hear me when I told her just 1oz of it so she gave him all 4oz because he kept wanting more. Will he be okay? I’m worried that his digestive system won’t be able to handle it 😩😩😩 His Pedetrician said to give him about 1oz of purée a day
