How to make baby sleep with a toddler at home

So my toddler is almost 2.5 months and she’s at home with me and the baby all day. We do a lot of fun activities and I constantly play with her which I love to do. But when it’s time to lay the baby down for a nap she’s so needy. I already give her so much love and attention but I can’t even take 15-20 minutes without her needing something to lay the baby down. 😒 it only works when she’s watching tv but I don’t want to turn the tv on 4 times a day

Right now I just have the baby sleep in the baby carrier the whole time because I just can’t get a minute of alone or quiet time to lay her down.

How do you guys do it? Any tips?
