We moved when our LO was 2 weeks old! And it was a hell
We had a removal company to pack the things, then my DH unpacked most while I and LO stayed overnight with his dad. (how on earth he managed it, I dont know!)
I would reccomend to have someone unpack all the stuff as well.
Also, a good idea is to book a room in a hotel nearby. Just in case something goes wrong (like when my DH came to a new house a day before us he had problems switching heating on).
Also, just in case ring a few removal companies as a back up. Basically, we had to move on Wednesday, removal company was supposed to come on Monday at 9 am to start packing (we have awful lot of stuff). So, 9 am-nothing, 10-nothing, trying to ring-phones noone answers. At 12 pm I started ringing other emoval companies (the original one still didnt arrive and office phone and mobiles are turned off). Thanks god I managed to get us another removal company, which managed to arrive by 3 pm same day, but it ment, that me 2 weeks after the c-section had to help packingup till 8pm wednesday evening. Anyways, wont go into details-it was pure hell.
So, just make sure you have some sort of back up (in our case, if we wouldnt have moved at agreed date we would have to pay penalty to 2 othwer sides (our byier and people we were buying from)
Hope you will have a more pleasant experience
