Supplementing with formula

I was thinking of replacing one feed a day with formula and pumping and storing that milk so that I can get an extra pumping session a day and not get too stressed about finding time to pump.

I just really would like to have enough milk frozen so that even if after six months I decide to breastfeed less and give more formula that I’ll still have milk saved for up to a year old.

Also I would like to supplement because he’s still seems tiny compared to other babies his age and maybe this will give him an extra boost.

I will be talking to his pediatrician about it as well.

Anyone have any suggestions or tips? Formula recommendations?

He’s had formula a couple of times and he seems easy with trying different kinds he doesn’t have a sensitive stomach or anything.
