142.I want you to know that I am eternally grateful that I have not just an amazing mother-in-law but an amazing babysitter as well. You always make time to help with your grand kids. It doesn’t go unnoticed or unappreciated.
143.They say that mothers are God’s angels sent to watch over you, and mothers-in-law are Satan’s minions sent to nag you. I think they got it backwards, because you have been far better to me than my own mother. I love you so much, and I wish you every greatness.
144.Today I would like to thank you for the help that you extended to me in all those years when I was new to everything. My marriage has prospered and grown amazingly with the help of your advice and your helping hand. Happy birthday! I hope you have the best day of your life.
145.It is your birthday and is the best time for you to celebrate life. You have given it another chance to make the most out of this life and I hope you take full advantage of it. Get that party dress out and celebrate! This is your time to shine.
146.Happy birthday to my mother in law. Any time your son/daughter annoys me I know you are the best person to call who will get me laughing in no time. I love how you are my first call whether its for good news or bad news. I hope it stays the same. Have a great day!
147.For me, you are my mother away from home. You make me feel like I belong, and I think that’s the best gift I could’ve ever gotten. This new home doesn’t feel foreign at all and for that, I am eternally grateful to you. Happy birthday to the best woman ever.
148.Happy birthday to the woman who made me her daughter, there is no greater gift than you could’ve given me because your love and support is all that I will ever need. On this blessed day, I hope all that you wish for comes true. I hope you have an amazing time.
149.I was going to get you an expensive gift this year mom-in-law, but then I thought long and hard about what you would prefer. It was a toss-up between shoes and cake, but in the end I went with cake. You’re welcome mom.
