Nurse with a toddler around?

I have a newborn and a 23 month old. Any tips on living your day with both? My toddler understands I have to nurse, but always wants to pat the baby which makes it tough, or she’ll do things she knows she shouldn’t And I’m pretty helpless. That and just general tips/encouragement would be appreciated, a little overwhelmed I guess. Toddler is super helpful and I get her involved as much as possible, just feel pulled and having a tough time balancing. Thanks
