How exciting famousmocknbrd!
I remember seeing my first baby on u/s and he was doing exactly what you said yours was doing, flips, cartwheels, just going crazy in there. I couldn't believe that I couldn't feel it!
Enjoy those kicks--This is my favorite part of pregnancy. I love it when I am drifting off to sleep and I feel a little thump, it's like my babe is saying goodnight to me... Or after I eat or drink something and then I feel him moving around enjoying the food that was sent down. It's pure heaven
oh, as for movement indicating temperment..my first was VERY active in utero and was a fairly high-needs baby because he was quite observant and internalized everything--still does. My second baby was more mellow in utero and was a very easy-going baby but when toddlerhood hit became more challenging because she expresses everything outwardly.
This baby seems more like my second--so I hope to look forward to an easy-going, easy-to-sleep baby but a more challenging toddlerhood.
We'll see I guess!
