The Nitro may not fully register a double bass . I never tried myself , but I have heard mixed reviews on that front . If you have a little extra , I ' d recommend going for the Forge , only another 200 and the module is light years better . Not to mention the overall feel is a lot less like a toy . <| sep |> Any sources that that ' s a great time of fertility ? For many women , they are still bleeding heavily in the first 46 weeks after birth , meaning it ' d be hard to implant and maintain a zygote . And if the woman exclusively breastfeeds it ' s quite unlikely like , it can be as effective as condoms to get pregnant again until the baby starts solids around 6 months of age . Obviously that ' s not to say it never happens we all know some Irish twins . It doesn ' t mean to not use protection . But I would find it hard to believe that anyone suggests that it ' s a level of high fertility immediately after birth .
