6 week old not sleeping much

Chanie • 26 year old model from London , first pregnancy and couldn't be more excited !!!!!

Hello, my little one has not been sleeping much these last few days. Perhaps 4-5 hours in total per day 😳 and thats usually an hour here, half an hour there and I'm a little worried. She's feeding constantly and is so difficult to settle she must be exhausted. She is so alert and is always moving her arms and legs frantically !!! What can I do ? I don't like seeing her like this . She must be tired!
