Nazly, that's exactly why I found it so stressful and difficult to adjust to and really could have done with the support when DS became mobile. Team, your Mum is definitely right. I feel like I missed out on that time really.
Like you Nazly it happened pretty fast, and the speed with which DS perfected crawling and pulling up was quick really. We have laminate floors like some of you, and they are a bit of a nightmare to be honest, but do have the advantage of being less likely to give carpet burns to little knees! We've improved with mats, blankets, cushions and bean bags placed tactically, plus I sit on the floor all the time now, rather than on the sofas.
He is a complete ninja and KNOWS the second you turn your back and knows what he is allowed, and what he is not allowed to have. The trouble is when you react to him getting something he shouldn't, you are giving him attention, so it rapidly becomes a game. He also wants things that Mummy has more than anything. Like mobile phones and keys and cables. To a certain extent it is better to watch him with some of those, rather than fight with him as he loses interest in them quicker. Equally you can use this to persuade him to play with his actual toys 
. Cardboard boxes have been a lifesaver too as they are hours of fun and a massive distraction. (Pampers sized boxes are ideal. Or medium sized Amazon boxes. However, be warned they can be pushed around and climbed on allowing access to places you think are out of reach!) We also have a travel cot set up in the front room as an emergency play pen. I don't use it much, but its good if I need to just plonk him somewhere and can't keep an eye on him.
To a certain extent there is only so much you can do to save his fall on the laminate. Bare feet is a big help to stop slips. So we have moved into trousers and footless baby grows. Despite being careful DS has ended up with loads of bruises, which was really upsetting at first, but I'm getting more used to it. The first time he got a bad one - a black eye - I found particularly difficult. I was terrified someone would say something! The thing is there is ONLY so much you can protect them and they do bounce quite well. Its just hard to adjust to it.
I think the first couple of weeks were hardest, as both DS and I got used to it. And obviously as his balance has improved he has learnt not to fall quite as much. He's only learned that through trial and error though.
RE: Bedtime. I've been reading everyone posting about sleep training quite amused as there isn't a cat in hells chance it would work with the way DS is. We never have had the same window of opportunity to try those tactics. DS has a magic self righting system where the second you put him down he rolls over, crawls or stands up. It would be a completely fruitless exercise trying to put him in his cot and shh him. He just wants to PLAYYYYYYYYY. I am not prepared to let him scream it out for any length of time (in part because I wouldn't be surprised if he escaped his cot). We have had to co-sleep which isn't ideal in the slightest. However we do have a routine in the sense that we have quiet time in the bedroom and wind down slowly. He isn't allowed to go crawling around. (Which can result in much baby wrestling). I have found that sometimes giving him 30mins to burn off a bit of energy before he gets over tired can be helpful too if he's really having none of it. Good daytime naps do seem to stop that being so much of an issue. He's generally easier to settle during the day anyway. He's not good settling around DH though. He only has to see DH and he gets hyper, so DH is getting banished a lot lately.
Beyond that I don't really have any great gems of wisdom for sleep as DS doesn't really have an off switch and we are struggling with it. I think we have just about got past the worst part of it where he would wake hourly and crawl and stand up with his eyes still closed, whilst he screamed. Hopes desperately. Milk and cuddles work, so I'm going with it. I wouldn't get any sleep otherwise.
DS has learnt to unscrew things and open my handbag (it has a zip with a long tag) in the last couple of days, so don't assume that they can't get into things just yet too, if you are thinking about baby proofing.
DH hasn't quite cottoned on to how much DS can do sometimes too as he isn't here as much. He often gets caught by surprise so its worth keeping half an eye on your partner and giving them a gentle reminder every now and then.
Oh and high chairs whilst out. DS has climbed out of them and onto the table before (the straps are generally useless). So watch that one too.
Hope that helps in some way. DS gets more awesome everyday as he learns to do stuff, but I've found this bit much harder than the newborn stage as he was an easy newborn and he's turning into a Tasmanian Devil. I had anticipated him being a little bit of a terror when a toddler and expected him to be difficult as a newborn so it really caught me by surprise and was a shock to the system at this point. If I'm honest I really didn't enjoy it at first.
