My little girl is 3 and a half months and has recently been making this straining noise. Sometimes she's got a dirty diaper but she even makes it after she's been fed and changed (and though I initially thought it sounds like constipation, this baby is definitely
not constipated

. I wasn't sure if maybe this noise replaces crying to some degree (I'm disappointed but not freaking out quite yet..). Anyone else have a baby making this noise & any idea what it means?
