Thanks for the tips re: paperwork. Will definitely print everything for the airport.
Good point on seat selection - BA app has allocated the two (for now...) of us 1A/C on the way out and 1D/F on the way back. Both currently on a A319, though could equally be a A320 or A321 on the day depending on load.
1. Which of these seats are designated emergency exit seats? I imagine 1A/C are, but are 1D/F also?
2. If these are emergency exit seats, assume we will not be allowed to sit there with an infant on the lap? If so, I may as well re-select other seats now to avoid being moved with no choice later...
3. Aside from emergency exit seating, any view on whether Row 1 is OK for travel with an infant, or whether Row 2 (with seats in front of us) would be somehow better?
I have zero clue about air travel with a baby at this point, so anyone with any tip on seats please shout!
