Aww, colic can be really exhausting for both baby and mummy, hang in there! From what I've heard among mums around me, Biogaia probiotic drops are quite well-loved for newborns, as it helps to balance the baby's gut and many noticed a difference after a few consistent days of use. My neighbour actually tried it for her little one and said the key is giving it daily and being patient, as it takes a little time to work. Some also mentioned that gentle tummy massage alongside the drops can make a lovely difference too, rather than relying on drops alone. That said, since your baby is below one month, it's really best to check with your paediatrician first before starting anything, just to be safe and get the right dosage for your little one's weight.
