4 month olds on cereal

Mom • My name is Raschel. I`m married and have a wonderful 4 year old son and a beautiful rainbow baby girl born nov 2016.
Just curious how much cereal everyone's 4 month olds are eating. I started mine with 2 baby spoon fills a week ago but she seems like she's wanting more. I just gave her a tablespoon and she ate it all plus a bottle! Thanks!
