Query: Good for colic

Hi. Love this sling. Tip: when facing baby out, you can put a bib through the arm holes and have it drape over the top. Easy to change out and give baby a fresh place to drool. We put my son in after he eats. He usually burps and it helps with the acid reflux to have him upright. He enjoys going out for walks in it as he can touch and feel the flowers and objects I bring close to him. Good idea to have an umbrella handy for walks as there is not the shade that strollers provide. It can also turn into a baby OVEN fairly quickly, so I use the stroller when it's warm out. Another tip, when baby is in the sling, I eat or do things in front of a large mirror. It keeps him entertained.
