Hey, welcome to YT!
How are his sleeping arrangements: crate, bed, ex-pen, etc? Jackson began sleeping thru the night around 18 weeks old but I would always pull his food/water up by 10pm, let him out one last time at 10, and then wake up around 7am with him. Now that he's over 1 year of age, he will sleep in pretty late with me, especially on weekends. This morning he slept until 10am with me and was let out at midnight.
