Hey. I'm shortly to give birth (very close to due date) and one thing that surprised me was how long it can take to get certain items of furniture/baby stuff delivered.
My husband and I were both a bit superstitious about getting things in too early, but I guess I assumed that when we did get around to ordering items (I'm thinking in particular of the buggy and the cotbed), they'd come pretty fast - like within a week or so.
In reality, most of the big items took at least a couple of weeks to get delivered. With the buggy we wanted to order (with lots of bits like car seat, etc), we were told it would be an eight week wait for the colour we wanted. One delivery from John Lewis took three weeks to arrange, then there was a problem with the delivery and it was delayed a further 10 days.
Everything's here now, but if the baby had arrived in week 36 or 37, we would have been very disorganised. So I'd say save yourself some stress, and don't leave ordering the bigger items until the last minute like we did.
Oh, and don't underestimate how tired you'll be towards the end. I breezed my 2nd trimester, but I found the third hard work physically (with a lot less sleep), so do factor that in when you're planning when to go out on maternity leave.
Best of luck. I've loved being pregnant despite all of the discomforts, and I wish you a very happy and safe one.
