Change of poo 👀

So gross but I gotta ask, my girl is one tomorrow she used to have gaps between poos sometimes firm. She has struggled with constipation recently I think mainly due to transitioning onto cows milk. But for the past week maybe now her poos are very soft sometimes now have bits of mucous in it? Not every poo but it does make an appearance, the smell can be a bit stronger to and I can’t seem to understand why. The only difference in her diet I could even think of is her fruit intake has increased. She’s not uncomfortable no pain or anything just my very happy little girl. Is this a normal part of getting used to foods? Has she had to much natural sugar from the fruit? Help 🥲
