Normal. Patience mommy. Its supposed to be messy. And if you give in to him just because he tales a long time. He will pick it up. Either you be patient and let him eat. Or you just serve him.biscuits to fasten the meal time. If i were you ill let him take his time.
BLW is indeed messier then feeding via spoon. for me, i couldn't stand the mess,so i didn't allow self feeding until they were much older
If a year old baby feeds himself perfectly i would freak out. :)
