perfectly normal! i am 11 weeks and i want to sleep all the time! nap when you can :)
I am 10 weeks today and constantly tired as well. I have been trying to rest during lunch breaks at work, going to bed shortly after my daughter, and sleeping in on weekends. If I can, I try to sneak away for a nap on the weekends. Hubby usually catches me and instead of leaving me alone wakes me up by saying "what do you think your doing". On the nights that I get home and I am so tired that I can't stand to keep my eyes open even walking, I take a quick power nap 30-45 minutes and this seems to help too.
hun i am in the exact same boat as u only i am only 8 weeks preg..i am so tired i could probably sleep stnding up if i let myself..all i ever wanna do is sleep..in everything i have read it seems pretty normal and usually calms down around start of second trimester but then again everyone is different.how did u feel with ur first pregnancy..and having to care for an infant while pregnant im sure adds quite alot to be tired about...
