Oo naman, safe yan at nakakatulong pa talaga! My baby is almost 8 din and side lying pa rin kami minsan, lalo na pag gabi or pag tired na ako, a few of us moms actually prefer it kasi nakakahinga kami better habang nag-bf. Just make sure baby's nose and mouth ay clear, and his body is aligned straight sa inyo so walang strain sa neck or spine, pero honestly by 7-8 months most babies na ay steady na enough para sa position na yan. Kung may concerns ka pa rin or parang uncomfortable si baby, good idea talaga to check with your pedia just to be sure!
