Babies wake — that in itself is not a disorder. What matters is how they wake and what helps. If the baby wakes, feeds and settles in your arms, that is ordinary and eases with age. If it wakes with a startle, arches backwards and being held brings no relief, physical tension is disturbing the sleep — and that does not resolve on its own.
Tension from birth keeps the body on alert. The baby then cannot move from light sleep into deep sleep without waking — and the more tired it gets, the harder falling asleep becomes. That is why a darker room and a later bedtime make no difference; this is not a habit, it is a body that cannot switch into rest.
The infant screening questionnaire maps three things at once — muscle tension from birth, the setting of the alarm system, and orofacial tightness that complicates feeding. It is usually their combination that keeps a baby from sleeping, and each of them is addressed differently.
