Baby bottles, breastfeeding bags for the bottles, thermometer, pacifiers, bibs, burp rags, baby bowls, spoons and forks, sippy cups, nail clippers, boogey sucker, diaper rash ointment, baby powder, baby lotion, baby shampoo, hooded bath towel, baby rags, high chair, play mat/rug, and for breastfeeding - some lanolin, hot and cold gel, and breast pads!
Diaper rash cream, first aid kit, a grooming kit, shampoo, gripe water is helpful for a gassy baby/hiccups.
