Sleeping patterns

[Clasik VH]

I have a 3 1/2 month old and she now feeds every 4 hours and sleeps 7 hours or more overnight, which may I say is AWESOME!!!! During the day she feeds and plays for half an hour after and then goes down for a sleep. But then she wakes up after an hour and plays for an hour whilst yawning her head off mind you and then goes back to sleep and wakes up after an hour which is then usually feed time. WHAT THE??? I am not sure if i should leave it cause its not so bad during the day or if i should try putting her back to sleep if she wakes up?? Seriously does anyone elses child do this?? What do i do??? Ideas anyone??? lol

Is she happy while playing and yawning? If so - let her do it, she's obviously not fussed and happy to resettle herself back to self when she's ready

I just posted this info in another thread, but handy to know that a babies sleep cycle is only 45 mins, so she sounds pretty normal to me!

Yeah shes happy playing i have to get her up though or she protests hehe,really only 45mins wow. Starting her on a routine now so she starts understanding that around 7-7.30pm is bed time and she does the same thing hour by hour but by 9-9.30pm she goes to sleep i feed her an hour later and shes down for the night.
