Aw mama, totally understandable ang worry mo, flat head (plagiocephaly) is pretty common sa 2 months, lalo na kung baby mo prefers one position kaya kelangan mo talaga makipag-consult sa pedia para ma-assess kung gaano ka-flat at kung may tummy time exercises or positioning tips na pwede siyang ibigay. The good news is maraming cases ito na naturally improve pa lang habang lumalaki baby at natututo mag-roll over, pero hindi rin dapat i-ignore kaya best talaga is get professional advice para sa baby mo specifically, some babies may need a special helmet but most really okay lang with proper positioning at tummy time, kaya better safe than sorry na ma-check ng doctor!
