Pretty much anything is normal! When my DS was little (less 6 weeks) he had seedy BM with every feeding. Then at one month, he went to BM every 3 or 4 days that were 'blow-outs"- huge messes. Now at 8.5 mon (on solids since 6 months), they are more formed and anywhere from 1-4 times a day. As long as there is no pain with BM, then you little one is doing OK.
