My 3 and a half month old was sleeping through the night 9-7:30am but recently he has been waking about 4:30-5am I usually give him his dummy and he falls back to sleep sometimes quicker than others! Last night he cried for ages though and would not take his dummy. I think he is starting to teeth so I gave him teething gel and a cuddle he went back to sleep eventually but I'm not sure if he's teething/hungry or has wind should I start feeding him at 5 again or will that cause his to keep waking up at this time? Advice please thanks! X
