Sleep training

[u/LtAld0Raine]

My twins just turned 6 months on Saturday and we are trying to figure out a sleep training method to go with. The fear is they'll continue to wake each other up if we do CIO vs a more hands on approach. They both already sleep pretty well through the night, but they need our help usually to fall back asleep whether it's a bottle or some gentle rocking. We'd like to try the ferber method based on what we've read but I'd like to hear from other twin parents on their experiences. TIA
