1 year old waking up at 5.30am

[DialMforMummy]

Hi,
DS is a very good sleeper, goes down at 7 pm every night and sleeps through till 5.30 or so. Until last week, we'd give him a bottle and then put him back to bed (I used to sleep with him from this time on but decided to break the habit).
After a bit of initial resistance, this worked and he'd sleep till 7ish.
The issue we're having now is that now when he wakes up, he doesn't really want the bottle straight away and then screams when we put him back in the cot (after he eventually had the bottle). As this morning he really was giving it the beans, I thought that maybe he was no longer tired and maybe that was the reason why he gets so frustrated and struggles to settle back to sleep.
The trouble is that he is actually still tired and I am not too sure what to do tackle this issue.
I hope I am making sense and maybe you have some helpful suggestions/advice/experience.

My DS did the same at that age. It lasted for about two or three weeks, maybe a bit longer. We gave up trying to get him to sleep again. We got up, gave him a bottle, then breakfast an hour later, and then back to bed for a nap at about 9. On some days we had to take him to the childminder anyway, and he would have a nap as soon as he arrived at 9.
We found that as he became more active, he would sleep longer in the morning.
I think it's a question of waiting it out, in the faith that it won't last for ever!

my 16 month ds wakes between 5 and 6am ever morning but if we give him a bottle he goes straight back to sleep for between 40 -90 mins depending whether closer to 6am or not. this is not ideal as it means i am then awake from this first feed as i can't get back to sleep, so am still exhausted! i am debating at the moment leaving him to cry this feed out but worried he'll wake up the dd1 and i dont think i have the strength as deep down i think he's waking as he is genuinely hungry. oooh they are such devils!!
