Louis, 24, is disappointed by the lack of support from his bandmates Harry Styles, Niall Horan and Liam Payne, reported Hollywood Life.
"None of the other One Direction guys have been to visit Louis since he had this baby, which has been upsetting to Louis. He knows that because the band has been on an extended hiatus, the other guys should have the time and make some time to come meet his new son.
"Louis is enjoying fatherhood and his life has changed a lot since Freddie was born. He wants to share his son with his mates, but he is still sad and disappointed they haven't been by yet. Louis is trying his best to be patient and understanding, though, and be the best father he can be," a source said.
