MO
Also called mo, 7MO, 6mo, 8mo, month-old
MO is short for month-old, written straight after a number, so a 7MO is a 7-month-old baby. Parents use it in post titles and quick updates about their baby's age.
How it's said
My 7mo DD goes to bed at 7pm, is BF, sometimes falls asleep on me and other times I put her down drowsy.
Hello I am really struggling at the moment with my 8mo sleep schedule.
Since 6mo his sleep has got worse.
