2nd time mummies?

Lauren • Mummy to Kameron & Emilie 😘
Hiya,
Was just wondering if you've felt your little ones everyday since you started feeling movements? 
I'm 17+1 and I've felt little one since about 15 weeks but it wasn't everyday but then the past few days it's been quite good. At least once a day but today nothing! It's stressing me out!
