Baby's 1st word?

my baby is 11 weeks old and for the past week my mom and my boyfriend have been saying that she said mama. i didnt believe them b/c i thoought it was just her cooing and making that mmmmm sound she always makes, but yesterday she started crying and she said mama, i was skeptical so i just kinda brushed it off, then this morning she did it 2 times while she was crying could this really be her talking at such a young age
