Bedsharing-Sleeptraining-Bedsharing

Hi! Baby is now almost 7 months! We bedshare when he turned 3 or 4 months because he gets frustrated when he can’t flip on his backside. Fast forward, when he was almost 6 months we sleep trained him to sleeping on his crib, we were getting the hang of it, but then summer happened! A lot of festivities and vacations interrupted his sleep training and now we’re back to bed sharing. Can I still sleep train him after summer??? Will it be harder or easier?? Any tips?? Thoughts? Suggestions?
