That's such a great and easy age to take a baby away - particularly when breastfed. I agree pop some pouches in your bag but also fruit (not from buffets), bread and yoghurts are easy food at that age.
In morocco clothes will dry super quick so it's easy enough to do a hand wash. Also their clothes are so tiny and it'll be warm so you don't need tonnes of layers - so you can easily pack 14 vests and they take up no room at all.
All in one UV sunsuits and hats are brilliant if you'll be on a beach/near a pool to keep them covered. Sun tents are brilliant but probably too big for your luggage allowance so keep an eye out when you get their for one (again if you are going to the beach). Buy and try suncream in advance to check their skin is ok with it - Boots own Soltan was great for my baby.
Pushchairs, you go to check in and get a luggage tag but then can actually keep your pushchair all the way to the departure gate so that makes life at the airport much easier.
Keep in mind though that when you land, your pushchair is likely to come out at the barrage carosel and so if you have a baby carrier pop that into your hand luggage.
I've flown loads with my two year old and 6 months was by far the easiest - not mobile and breastfed so I fed her on take off and then she slept for 1.5 hours each way. Breastfeeding is great if their ears start to pop to keep them clear.
Don't stress, a little planning and a holiday with a baby is very straightforward indeed and lots of fun.
