When my youngest was first born I did notice he was awake at the times he'd been most active when I was pregnant but this changed after a few weeks, he was also pretty active in his sleep at first, moving around and sometimes waking himself up but after a month or so he started sleeping more soundly
When DD was in utero I was told she was very very active. And sure enough she never stopped moving as a baby, she was always kicking and waving her arms around. Couldnt sit still - we actually worried about it at the time thinking she might have some neurological problem (which of course she didn't - first time parent worry syndrome)!
However she's always been a brilliant sleeper thankfully. Probably because used up so much energy during the day. I dont think an active baby = poor sleeper at night. However she stopped having daytime naps at about 1.5 years old which was a bit of a pain!
Im 36+3 and baby has been very active since the beginning, with a lot of hiccups; dp gets terrible heartburn/hiccups and so we think baby has taken after its father in that respect, which although a shame is also quite delightful to ponder upon
DD is 7wo and was a right little wriggler onthe inside. She's never still on the outside to be honest but you'll be pleased to hear that she still sleeps rather well, if not wriggly. I'd lay her on the bed next to me this morning whilst I listened to the radio for an hour and she's turned nigh on 180 degree in her sleep. So rest assured that even if your babbie never stops moving, they can do a lot of it in their sleep
DS was so lazy inside. I didn't feel him until 23 weeks and was monitored 5 or 6 times for reduced movement when I was pregnant. On the outside, however, he is a little hurricane! He has always been very active, crawling at 5 months, walking at 11 months and never stops, people comment on it every day. He has always been a very good sleeper though, at 23 months he sleeps 7pm-7am and still has 2-3hrs at lunchtime. I shall be interested to see what DC2 will be like.
