Help please


Hello, so my baby is 5 weeks old and today she woke up earlier than usual and since then she has been acting really “needed” like she only wants to be laying on my chest and on my breast but I’m wondering if she’s eating or just having me as a pacifier I tried giving her one but she doesn’t want it and she would go to sleep but only for a couple of minutes… do you guys think that she’s not eating enough that’s why she keeps trying to eat or maybe my breast milk is not making her full
