A soft carrier like the Solly Baby or K’tan. Babies as small as 7 lbs can be carried this way. It’s an instant soother for a fussy baby, frees up your hands, and allows you some freedom of movement while keeping baby close. Trust me. You can do almost anything while wearing your baby. Like make a meal, go to the bathroom, and run errands. My baby still is soothed the best this way when he’s in a grumpy spell.
