First time mom...

How do you ladies handle when your baby hits a growth spurt? My little one hit one at 3 weeks and was eating every hour and a half and needing changed every 45 minutes so I was exhausted.... she’s now 6 weeks and here we go again... she’s eating like crazy, only sleeping in 15 minute power naps, just wants to fuss and won’t go to anyone but me.... i feel like I’m going to lose my mind and I know it will be over in a few days but just need some motivation to push me through this 😭😭
