The only time dd seems really tired is on a Sunday night after a weekend with us, it's not like we go walking up Snowdon or anything just mooch about doing our thing, walks, parties, friends, museums, park, biked etc.
I got sick of the amount I was told how "tired" she would be on starting school....she's not. She's full of beans.
I put her to bed at 7.15 the other night as i thought she must be tired, everyone says so. She was up raring to go at 6am, unacceptable for us so bedtime was put back to 8pm and she woke at 7.30 as usual.
the only thing I can put it down too is excitement maybe? Or not being outside as much as she would be with us?
