Aww, ang sweet mo for offering! Depende talaga sa age ng baby, if newborn pa lang, maybe a co-sleeper or bassinet muna, pero kung ready na for independent sleeping, a crib with firm mattress talaga ang safest. A few of us mums prefer buying new or certified secondhand para sure sa safety standards, especially sa slats and paint (walang lead), pero I understand din kung budget-conscious kayo, just make sure walang cracks, sharp edges, or missing parts po! Goodluck sa inyong baby!
