Hi there, thank you for your question and Happy new year.
It is difficult to make arrangements with people that we do not get along with. It is unfortunate that there is hostility between you but you are right to rise above it for as long as contact is in the best interests of your daughter.
As father shares parental responsibility with you, you should keep him in the loop on all milestones and important events in your daughter’s life. Imagine being in his shoes. Would you like to know if your daughter is being christened? You will not be breaking any laws if you do not tell him but you will be setting a precedent that he may follow. When your daughter is in his care, he may arrange important things and not care to inform you. Informing him of the christening is not an open invitation for him to be involved or even invited, that is your decision.
Regarding passports, you may apply for one as you have parental responsibility. It is always advisable to inform the passport office that you have separated if there is a risk of your ex obtaining another passport and attempting to take your child abroad without your consent.
