In fact, all the formula milk is the same.
How to choose? It's all the same: it's suitable!
I've heard that some big brands are not constipating, your baby is not constipated, but my baby is! So try it all the way to the end, but don't recommend switching too closely as it takes time for your baby's gut to adjust.
The only thing I would recommend is that there are some partially hydrolyzed formulas on the market that are more suitable for human milk b to top up, as the hydrolyzed formulas are easier to absorb and less taxing on the stomach of a human milk b.
Myth: If your baby is 7 months old, you must switch to stage 2 formula, otherwise it will not be nutritious enough.
Stage 1 formula is the most nutritious, so there is no such thing as "if you are old enough, you must switch to formula". In fact, many western countries have only one stage of formula. Why are there so many stages of formula in Hong Kong? It's all about marketing (laughs)! So if you have a can of No.1 in your house, you can switch to it before you eat it!
Note: ⚠️ month olds can have a smaller stage, but you can't turn it back!
