It really depends on the child. I have a 9 month old who has weaned from her morning naps at my hand. I kept her on them for the first few months she was here, then slowly eased them out as her afternoon nap was a dismal 45 mins, then another 45 at 5pm. She was exhausted by the series of short naps, so I changed it to one long one. She's golden now She stays awake easily until 12pm and sleeps till 3pm and is happy as a clam. However, some kids are sleepier. If your little one needs a morning nap, by all means, keep it up. But it could possibly be that the morning nap is causing problems at other sleep times.....along with mum not providing any consistency. Would she be receptive to a conversation about a strategy? I know my youngest stopped morning naps at 6 months and stopped napping altogether at 1.5 yrs. He just wouldn't sleep at night. Removing naps resolved the issue.
