Baby kicking

Mercy • I'm 27 years old and me and my husband are expecting our 2nd baby in March. Our daughter is almost 2 and we are excited to be giving her a sibling!
I'm a FTM and I was just wondering if it's normal for baby to be super active one Week and not the next. She was kicking me outwardly and now it seems I only get one kick here and there and feel a thumping on my bladder every once and a while is the thumping sensation also baby?
