I'm a first time mom and my daughter is 5 weeks old. She has been fussy all night and it is 3am now! She eats then goes to sleep but then less than 30 minutes she's up and fussing again. I've burped her trying to lay with her she's sleepy but I'm thinking something else is wrong to. Idk what else I should do. I'm also worried if she has fluid in her lungs she's breastfed and at times sounds like she's gasping for air when she's not eating and I put saline drops in her nose and she inhaled very hard each time I'm just worried...and tired!
