Uhg I'm so tired I don't have time for myself anymore I have a 3 year old and I'm constantly yelling at him for not listening to me I feel bad for him he's a sweet little guy even though I always get mad he's always hugging me asking me if I love him and ofcourse I say yes and I start crying again and say sorry to him. ☹️ my 3 weeks old who wants to nurse every hour and now I just gave her fomula so I could take a rest for a little bit and to top it off she's still constipated 😩 I hate feeling like this I love love my children very much but I sometimes feel like I'm so overwhelmed. 😰
