Ok guys so a little back story in 2014 i gave birth to my girst daughter st 37 weeks she weighed 4lbs 6oz but passed away after birth with ancephaly. 2015 i gave birth to my 2nd daughter she weighed 4lb 14oz but was 6 weeks early. 2017 i gave birth to my 3rd daughter at 39 +5 and she weighed 7lbs 11.8oz. Im now 37+4 with my first boy and he is measuring 2 weeks behind but has been measuring up yo date this whole pregnancy until recently . He is said to be 5lb 13oz , but my ob is saying its normal since i make small babies , which i personally dont see how. My 1st had the whole top of her skull missing and my second was 6 weeks early. Im concerned that their maybe a reason he isnt growing on track as he was before
