How to do 2 kids at home???

Katie
I've got a 9 week old and 3 yo, both boys. Big brother is adjusting OK but daily is a struggle of him playing on his own for feedings and while I put baby down for a nap.
What do other moms do? Baby likes to be in his Ergo sometimes and to lay on his activity mat sometimes and big brother will sometimes play on his own but there still TOO MUCH crying/fussing ...
Thoughts?
