Unfortunately, a single bottle is never enough when it comes to feeding a baby. First of all, you need to have bottles of different sizes that will be appropriate for various purposes. If you want a bottle for the newborn, you will need the tiniest bottle with a volume of no more than 125 ml. If you’re looking for a bottle for a toddler, you can easily get a bottle of around 300-350ml. You will need to have a measuring scale or a measuring cup to check the amount of milk your baby drinks every time and how much you need to prepare.
Of course, if you use both methods of feeding – breast and bottle milk, then you will probably need no more than two bottles during the day. However, if for some reason your child cannot breastfeed, you need to get at least six bottles to ensure you have enough milk for 8 feedings per day.
