is there such thing as a baby growing TOO fast??

Addie

my 12 week old baby boy is in yet another growth spurt and I don't know how my body is keeping up with milk production honestly lol he's grown 10 inches since he was born. I don't know his exact weight right now but it's probably around 15 lbs. I'm glad he's doing well but I'm a little freaked out by how fast it's happening! i just had to buy a new car seat, stroller, and bassinet because he's outgrown his old ones in just 3 months. this normal???
