Toddler drink formula from bottle

Hi mummies, my baby is turning 2 in 2 months time. He still drinks formula about 4 times a day and still from bottle. Karihome formula. But just got to know from a post that kids their age doesnt need to drink formula at all or atleast still drink but not from bottle ( eg sippy cup ) As i've been growing up with surroundings that still bottle feed up till they got into kindergarden atleast. And i thought ot was normal to bottle feed as every child in the playgroup still drinks from bottle. Thankyou.
