Holls Stop fretting, they are all different and what works for one child won't work for another. Our naps are just changing from short and frequent to longer and structured, so have moved into the cot (if we are home, but I do try to plan the day around being in as often as possible for naps).
We have 2ish hours at 9am and 2ish hours at 1pm - both in cot. She then needs another nap somewhere around teatime, but this is often a battle and can vary from a 20 minute powernap to 60+minutes that result in me having to wake her up.
Topsy You are brave. Am I right in thinking that babies don't get their own seat on the plane? I've not flown with a baby before. Fingers crossed for a sleepy baby on travelling day.
Ella I've used those flavoured water things in the past. I really just think they are watered down fruit juice. I recall with DC3 he completely bypassed all baby cups. Since my older children have sports beakers of squash on the go all day long, it doesn't take baby long to find and figure them out. So he just went onto beakers of squash very early.
Nazly Something Topsy said reminded me, one of my friends son carried his Mums pillow case (unwashed, so it smelt of her) around when he first started nursery.
