If you are considering buying a crib for your baby, you should check it from all the joints. Make sure it is not damaged from anywhere and all the joints are firmly in place. Check thoroughly from the inside as you do not want your baby to get hurt. If it looks in bad position, do not buy it.
Buying used clothes for babies is always recommended but you should not compromise on the quality. While buying used clothes, make sure that the garment is not torn from any place and there are no holes as you do not want your baby to catch cold.
If you are going to buy used pillows and blankets, you should wash them first and make sure they keep your baby warm. Remember that you should not buy heavy blankets and prefer buying the light ones.
You should be very careful while buying used infant bath seats. Check the quality very carefully and before placing your baby on it, make sure it is strong enough to hold your baby.
