Graco Children's Products is recalling 1.9 million infant car seats.
The recall follows pressure from U.S. safety regulators.
Earlier this year Graco recalled 4.2 million toddler seats because the harness buckles can get stuck.
But it resisted the agency's demand to recall the seats for infants.
Buckles can get gummed up by food and drinks, and that could make it hard to remove children quickly in an emergency.
