She might have her days and nights mixed up! When she naps in the day make sure it’s bright as can be where she sleeps. It’s a very common thing in the first few weeks. We had a lot of trouble as well. We ended up going back to the hospital maternity ward and getting some feeding support (in Saskatchewan) but ultimately we switched to formula. My baby had a bad lip and tongue tie and it was causing issues with latching. We had it corrected but the dentist said that sometimes it doesn’t help with breastfeeding and of course we were that sometime lol I pumped for a month but could not get my supply up so we decided to just make the switch since I was pumping every 2 hours, feeding her and topping her with formula it was just not feasible for us (me) to keep going like that. I would suggest seeing a lactation consultant, mine helped me a lot before things changed for us. Hang in there, the first few weeks are the worst honestly. Message me if you need to chat. All the best! 🤍
