The shelves are empty.
Parents have created online groups to exchange, sell and suggest where it is possible to get compensation.
American mother Jennifer Kersey hurried to the store to buy some cans for her seven-month-old baby, but was horrified to find that the shelves were empty.
- This is about babies, who must be able to eat, says Kersey.
The shortage arose in connection with one of the largest producers of infant formula discovering bacteria in a production plant.
Production was shut down and products were recalled from stores.
This led to disruptions in the supply chains, which were not flexible enough, which in turn also affected more producers.
According to the news agency Reuters, 40 percent of the infant formula that is usually in stock is now missing.
More stores are now rationing how much each customer can buy.
The problem has been raised at the highest level and President Joe Biden now wants to facilitate the import of infant formula.
- We work very, very hard.
There is nothing more urgent that we are working on than this.
