dd is 5 weeks olds tomorrow. She seems to get a lot of comfort out of sucking on her bottle but not drawing any milk out. anyway I gave in to buying a dummy. really have always been against them but thought she needs to be happy and content. We only started her on it yesterday but im wondering whether it's normal for her not to hold it in her mouth properly to start with? it falls out easily and she has a mild tongue tie so I'm wondering if that's why?
