DD 3months not eating and sleeping more

[moomoo2013]

Hello Mumsnetters,
DD is 14 weeks up untill about 3 weeks ago she would drink none stop up to 5 bottles a day 180ml and only got sleepy at 8pm ish and then slept through the night .

Now shes not drinking as many and has hour 2 hour plus naps in the day but continues to sleep throughout the night.

Shes exactly the same in personality happy laughing smiley alert but just gets grouchy and naps more.
Any ideas could there be something wrong or was the uber drinking just a growth spurt?

any replies will be helpful
Thanks

If her personality hasn't changed and she's still producing wet and smelly nappies in the normal amount, I wouldn't worry too much about this. Given her age, it's likely that she's simply moving from the unsettled, tiny tummy "newborn" phase into a more settled, mature baby who can manage longer gaps between feeds. Also, at this age she will be growing quite quickly, a process which can be tiring. As long as she's gaining weight at an adequate rate you should relax and enjoy the break you get when she naps!
