If you hear your baby make a "neh" or a "nah" sound that means it's feeding time. The most important part of this is the "n" sound at the beginning, so listen for that.
Time for bed! The sound your baby will make when she is tired is similar to the noise produced by yawning, and her mouth will form an oval shape. Try these tips to help your little one nod off.
Get out the cloths; Baby needs to be burped! The "eh" sound is produced when the muscles in Baby's chest tighten. Sometimes you will hear a more repetitive, staccato "eh-eh-eh-eh."
"Eairh" means Baby is gassy and needs relief. It can also sound like "eeerrrhhh" or "air." You'll recognize a lower and more urgent sound when the muscles around Baby's abdomen constrict. If you haven't been burping Baby at the "eh," you will soon hear "eairh."
When Baby is experiencing discomfort, you will hear a breathy "heh" sound. Sometimes, this will be a repetitious "heh-heh-heh" or "ha-ha-ha-ha." Now, you must assess what's making Baby uncomfortable. Is she hot? Cold? Need a diaper change?
Having trouble? Try to discern what Baby needs before he dissolves into sobs or change Baby's position. And if you hear more than one "word," act on the one that is most dominant or frequent. For more info, check out the Dunstan Baby Language DVDs.
