Pumping schedule

Hi! I'm a FTM to a 5 month old. I went back to work at 3 months pp and pump during the day while baby is at daycare. When we are together he is breastfed. I'm wondering if anyone with experience could talk to me about what pumping will look like long term and when we start solids. I currently pump 3x at work, every 3 hours when he would normally eat. Is this how it will always be? Will I be able to pump less during the day in the future and how will I know when I can remove a session? Feel free to shoot me a message if thats easier. Thanks in advance!
