if it helps at all i was horrendously tired and sick when preg with Alyssa and this time ive not been as bad, i havent found it that hard, since alyssa is still young (16 months) she still naps so if im tired i can nap with her and shes easy to entertain now so i dont have to try too hard to keep her occupied, a cardboard box keeps her happy for ages lol so i think its not that bad being pregnant with a toddler, plus shes too young to notice or get jealous too much etc so i can honestly say that so far so good, this heat is the killer rather than the toddler when your heavily pregnant haha, oh well only 8 weeks to go!
