5 weeks old and bresfeeding only 5 min

My little Eloise is 5weeks and 1 day today. I'm breastfeeding and till now everything was ok, from yesterday she stays only five minutes in brest and than she doesn't want more, I try with her but it is impossible. I tried to let her 3 hours without feeding, the same thing. I think I changed her diapers normally.

I don't know I'm so in stress, I will try to make an appointment with pediatric but the situation of covid in mu place is very bad.

I'm so in stress, my husband says we have to gave her formula because se maybe doesn't like your milk, he increases more my stress. I want so much to breastfeed her 😔
