Yes he will be going. He is named as the father on the birth certificate. Can he take their son abroad without the mother's consent? The mother doesnt have a passport and so in the event of a problem she would be unable to go and help. They have been asking about this since he was a baby.
One of the reasons for going together is so that they can share the childcare and his father can have time 'off' leaving Luca ( my grandson) in the care of his other grandmother who is deaf and doesnt hear unless she is facing someones lips. One hears about abductions, accidents etc which my daughter is very anxious about. She has her own feelings of anxiety about travel abroad and flying and so feels particularly concerned about what might happen in the event of an accident.
The other grandmother has also stated in the past that she might just go to New Zealand on holiday and not come back.
She has also suggested to her son that they forge my daughter's signature in order to obtain a passport and take him with or without consent.
For all the above reasons my daughter does not feel confident about letting her son go on holiday abroad with them.
About 58, still working.
