MS. Jones, I've had several times in my life playing bass where I simply walked away for a while. Life can get very hard, can spin your priorities, and sometimes these things become suddenly more important than those things.
I took my 'walkabouts' away from the damn things as normal, as I just didn't even want to see one, much less play, or especially go back to a band.
Usually, over time, the yearning would begin to manifest itself, and little by little, I'd get intrigued enough to begin again. I took this as a normal turn of events, as for much of my life, I obsessed myself with basses, playing, listening, the whole deal, often to the exclusion of everything else in my life, a large mistake, but hey, my hair was on fire to do it, and I was determined to do it, big time.
I found it was like riding a bike, you get rusty, but you don't forget. And often, the time away spurred different ways of thinking or imagining different concepts. This was very healthy for me.
Infants and toddlers are 25-hour-a-day job, and no wonder you're tired and a little de-horsed to play bass. Family comes first, and children are at the head of that line.
But I'd dare say life will adjust, you'll feel the itch calling you very quietly one day, and you can begin again when you're ready to do it at whatever level suits you at that time.
All the Best,
JW
