Its up to you. After about 10 months i gave my son formula made with tap water as he was drinking tap water and cooled boiled water would not kill of any germs in a bottle anyway.
I also gradually stopped sterilising bottles and did half and half for about 2 weeks.
Hes now 13 months old and we managed to just change to cows milk overnight, no gradual change im pleased to say and life is so much easier.
Im glad your daughter liked the drum. My son loves dancing to the music on his.
