Don’t leave your baby inside the room for longer periods even when they are asleep.
Avoid as much as possible in putting baby to sleep on their tummies esp. at night. Once they get past their 4th month stage, the risk of SIDS will become lesser.
Never buy over-the-counter medicines for your little ones; always consult with your doctor.
Do a little outdoor strolls; not only do babies need it, they would also love to see varied sceneries once their visions start to work at a longer distance.
Always make sure all products used on your little munchkins will be free of harsh chemicals.
Observe patterns of their needs & behaviors – this way, it will be so much easier for you to address their cries (and your instincts are of a great advantage as well).
