Firstly, congratulations!
I’m assuming as it was planned you already have folic acid/a multi vitamin with folic acid in?
Don’t feel like you have to get everything sorted in a hurry - pregnancy takes aaaaaaaages and by the time you get to the third trimester and want to have things sorted, you’ll feel like you’ve been pregnant half your life! You have lots of time to get travel systems/cot etc sorted, so do take your time to shop around and make sure you ask other people for opinions - e.g. some buggies are much easier to fold one-handed than others, which makes life much easier! Definitely don’t rush out and buy lots of baby clothes at this stage. Lots of people will give you things for your newborn, and they grow out of that size in less than a month (sometimes in days!), so you don’t want to have a tonne of stuff that you won’t use. I’d strongly recommend accepting hand-me-downs - nobody will see the vest your baby has under their grow, so who cares if it’s new? It’s going to get covered in poo explosions anyway!
I always assumed you made a doctors appointment when you were pregnant, so I did. I made an appointment, and then felt like an idiot when my GP was like “ok, so you’re pregnant. Why are you here?”. In my area you were supposed to give your dates and ask for a booking in appointment with the midwife for about 10 weeks. This time round, I phoned to ask to see the midwife and was told that it’s now done directly through the hospital and they have an online form that you fill in. Phone the receptionist at your GP and ask them what you should do, and do this as soon as possible as they’ll need to get back to you about your booking in appointment and first scan.
You will be amazed by how quickly you cope once your baby arrives. When I was expecting DD1, I had no experience whatsoever and was rather nervous about how to undress a baby without hurting them/not supporting head enough. I had no idea how much they needed to sleep/eat/be entertained. The thing is, the early days are so incredibly repetitive (you’ll be feeding them every 2 hours or so, probably changing their nappies about the same) that you actually become an expert quite quickly!
Don’t be afraid to ask for help. Experienced mums will have been there, done that. They know what’s normal and can tell you if something isn’t.
I was not ready for how crap I would feel 3 days post-partum. The hormonal swing was so much more intense than I’d expected, I felt like I’d been hit by a big miserable bus. I was sobbing, and when my DDs nappy leaked, I just couldn’t face it and was seriously considering getting scissors to cut her clothes off to make it easier. My breasts were enormous and felt like they’d been filled with hot concrete, and they were so swollen my DD couldn’t latch and was getting sprayed in the eye! Honestly I felt like a total failure of a human being. Alas, this is totally normal. It should pass very quickly, the next day I was fine (except for the painfully swollen boobs, they took at least 5 days to feel better).
