Difficulty in sleeping at night that affects morning routine

Hi Mommies, Need opinions pls. My 7 months old twin baby girls are having difficulty sleeping at night. Nap nap 1-5mins only. Literally, they went to sleep morning 5am or worst 1pm in the afternoon and woke up 5pm or 5:30pm. We are all struggling, the babies, me and daddy. Our problem is their activity in the morning is gone. They will eat 6 or 7pm after waking up and take a bath. Is this okay? Do i have to worry bout bathing them at night? Or if you have any advise. Thank you! #1stimemom
