I think rather than removing her from the application, just explain it in LOE. Because spouse and children are added post e-APR only if you get married later or the child is born after you get PPR. There's still a chance, even if it's low, that could receive your daughter's passport before 3 months. Then you are good to go.
However if you don't get it in time, and despite explaining it in LOE you get rejected, the fee you would've paid won't be refunded.
If you are not willing to take that risk and have score in 440s or above, consider declining ITA and aim for draws in late May/ early June.
