Aw, napakahirap yan mama, lalo na at 7 months pa lang, dapat sila matulog ng mas mahaba para sa development nila! One of my mum friends' baby din ganyan, napakaligtaan at restless, at naging okay lang pagkatapos namin check kung comfortable ba talaga ang sleeping space (temperatura, diaper, o kung may discomfort). I'd suggest din checking with your pedia kasi sometimes may underlying thing na nagpapabago ng sleep pattern, like teething, o milk sensitivity, o digestive issues na hindi obvious. In the meantime, try consistent nap routines (same time, same calm environment) kasi sometimes babies are just overstimulated. How's baby otherwise, okay lang energy at mood?
