What is this a sign of?

[1mum1]

After and sometimes during a feed my daughter is sucking in her top lip with her tongue and has now started sticking out tongue but leaving the tip of it in her lower lip (hope that makes sense). She does the top lip one an awful lot - anyone know what this is?

Thanks for any advice x

its normal, dont think there is a name for it but some babies do it when they are hungry others do it after feeding. She could just be discovering her tongue and outer mouth properly. I wouldnt worry if I was you, if you notice it gets red from being red, put some vaseline on it while she sleeps.
