Подойдут ли бутылочки от другого бренда к моему молокоотсосу? Помогите, пожалуйста!

I know this a long shot but since im pregnant with my second ive dug out my old breast pump which surprisingly still works but i unfortunately dont have the bottles it come with ive tried today to buy the same brand of bottles for a newborn but they dont fit 😭 im just wondering if anyone knows what size would fit in as buying a whole new kit is £132 but they dont do the bottles separate or at least i cant find them separately
