It was seventh time lucky for Lampard as Chelsea snapped a six-game losing streak since he assumed a caretaker role last month.
The Blues were pegged back at the Vitality Stadium when Matias Vina cancelled out Conor Gallagher's opener for the visitors but Benoit Badiashile and Joao Felix scored in the last ten minutes to give Chelsea all three points.
Chelsea have moved up to 11th on the table, far from where the club are used to being, but Lampard welcomed the feeling of winning again in his 100th game as a Premier League manager.
“They should enjoy it and we’re happy because when you don’t have that feeling for a while, it gradually knocks you down,” said Lampard.
“It was very evident in the dressing room from coming in that there was a lot of picking up that needed to be done and unfortunately you need results to come in line with that to keep you stepping forward, so that’s been tough.
“Today was a nice small step forward.
“The lads are all human, we’re all affected in similar ways when you’re not winning games or you don’t feel like you’re at your best and the only way to get through that is to fight and to work through it.
“I’ve been in relative periods where they’re tough, so absolutely they should enjoy tonight and have a beer or have a glass of wine or do whatever they do.
“But we cannot take our foot of the pedal in terms of trying to take steps forward until the end of this season because it’s important.”
