thank you for getting back with the developments. I totally understand that the entire situation is scary and it puts you under stress.
2. in regards of your documents- the best would be to ask the German government to demand the documents from the first country(Dublin one) you entered, however they might say that this is your duty- so try it but it might be the case that the first country will have to send it to yourself.
3. Yes this is very difficult, but if your partner and the father of the child has an apartment then you could also make the deal with the camp that you stay with your partner and just collect your post etc. at the camp until you have not found a bigger place.
I hope this could help you Grace, but do not worry they cannot apply Dublin if your partner is German and you are sharing custody.
If you need further guidance feel free to approach us.
