Welcome to the forum, Mariah!. :) I'm glad you've been bitten by the betta bug. You will have so much fun watching your little pal grow up.
For your baby, since (s)he is so small, I recommend New Life Spectrum Small Fish Formula .5mm pellets. These pellets are seriously small so they should be really easy for your betta to eat. Feed only 1-2 at a time although I admit it will be very hard to just pick out a few. When your betta gets bigger, I'd recommend New Life Spectrum Betta formula pellets or Omega One Betta Buffet pellets. Both are really good foods.
It really helps to have an adjustable heater too because on the hopefully rare chance your betta may get sick, you may need to turn the heat up higher than normal.
