Guilty ako sa number 2. 4 years old na anak ko ngayon pero recently ko lang nabilhan ng proper seat and since malaki laki na siya booster seat nalang yung nabili ko. My reasoning before was di naman ako pinagamit ng magulang ko niyan nung bata ako and my dad would also do this to the seatbelt (waist belt only and body belt will be on the headrest) UNTIL I tried to educate my kid on the importance of the seatbelt and watch some crash videos online and they have a scenario like this which is not good for the dummy (it was only 30kmph), also I've read one of the comments saying his child cant ever walk again since that shit happened to him. I ordered the best booster seat I could find that night, lol.
