Yes, you are right in your expectations, you will need to do each outing as if it is a campaign. But that doesn’t mean you need to worry about it – you will find that in a few weeks it becomes second nature to you.
If you have friends or family who already have babies then you can check with them what they find is essential to take out, and you will no doubt work a lot out for yourself anyway, but here is a selection of the things you may need.
Take enough nappies for the length of time you’ll be out, plus one or two extra nappy sacks for the used nappies, wipes and any cream you use. If you have the space, a portable changing mat is useful, but you could get away with a towel if you really have to.
A change of clothes in case of disasters, and a toy or any recent baby gifts that you know will distract your baby are also useful; a woolly hat for winter cold and sunhat for summer are a good idea to have in the bag all the time ready in case of need.
If you are breast feeding, you may like to have with you a shawl to cover up if you can’t find anywhere really private when the baby needs a feed.
You will work out what other things you need, but this gives a basic idea. The days of popping out with nothing but your front door keys are long gone!
