Naiintindihan ko ang worries mo, mama, it's stressful when teachers keep flagging something kaya nag-doubt ka na rin. Honestly, yung daycare aggression thing isn't super rare; a lot of us moms notice our kids act totally different sa school vs home, kaya dapat talaga makipag-consult sa pedia para ma-rule out kung may sensory sensitivity siya (ang sikip, ingay, init seem to trigger him talaga). Hindi ko sure exact price kasi depende sa clinic, but usually pedia consult is around 500-1500 pesos depending sa location, at kung kailangan ng formal assessment or evaluation para sa developmental concerns, mas mahal na yan, best ask your pedia directly or call ahead. The good thing is, pag may actual concern, may interventions na available, at most of the time maraming parenting strategies na makakatulong din, so don't stress too much na basta makipag-consult na lang. One of my mum friends din had similar situation with her son sa daycare, nag-check out siya, at turns out it was sensory stuff, and ngayon naka-manage na siya better with some tips from the pedia.
