UK Passport stuck in Europe

Hello all,

I have a 2-month old daughter whose UK passport has been issued but is with DHL since the war broke out and is stuck in Belgium with “shipment on hold” status. My wife’s passport is stuck there as well (as part of original documents that needed to be shipped to get my daughter’s first passport).

I read on Reddit that some shipments have started coming in (I got a Temu parcel which was ordered two weeks back as well - tracking shows flight with the shipment came in on 7 March), does anyone have any insights when DHL might start moving or what I can do alternatively to get the passports back?
