kylza, firstly congrats hun! i am so happy to see your UTD! hopefully more follow you from the 1-6 month ttc thread.
i think you should be fine with nephew i pick up my boys and their both 15kg and 11kg. just make sure you dont lift anything too heavy and if you need to rest make sure you do, overdoing it can make you exhausted. i moved when i was pg and my dh and my daddy wouldnt let me do the big things they told me to go unpack lmao! i hope you have a healthy and happy pregnancy xxx
