Pumping question past 12 months

So here's a question for everyone: my little one is 12 months old next Saturday (one year strong, in part thanks to you lovely ladies!) I have no desire to wean him; I plan on letting him nurse as long as he wants, really. He goes to daycare during the week and is taking 1-2 4oz bottles. I would LOVE to stop pumping at some point but wasn't sure if it's possible, without hurting my supply or if it will make him wean sooner or what. He still nurses 2-3 times at night and during the day, I just let him nurse when he wants so, sometimes we nurse once in addition to his good morning and goodnight feeds and sometimes he nurses 4+ times. Any advice, mommas?
