LOL Mel... Matilda did this last month too. She would have her bottle & then be up and talking, giggling, screaming for around 1-2 hours until she would finally fall asleep & nothing we did would change anything. We moved her bedtime back by 30 minutes and then we eventually gave that up entirely and just watched her & only put her to bed on the 3rd tired sign and she started going to sleep quicker & quicker & now her bedtime is around 30 minutes later than she was going to sleep before and she goes to sleep without a peep.
